**To write 78,000 in scientific notation:**

- 70, 000 = 7×10. …
- 7.8×10
^{4}(Note that 78,000 is a whole number, so we dropped the zeros)

## How do you write 85000 in scientific notation?

As a second example, it is quite correct mathematically to write 85,000 as 85 × 103, or 0.85 × 105, but correct scientific notation would demand **8.5 × 104**.

## How do you write 73000 in scientific notation?

**Explanation:**

- 73,000,000.
- 73×106.
- 7.3×10×106.
- 7.3×107.

## How do you write 84000 in scientific notation?

In scientific notation, a number is written as the product of two numbers: a coefficient, and 10 raised to a power. For example, the number 84,000 written in scientific notation is **8.4 X 104**.

## How do you write 67000 in scientific notation?

Write 67,000 in scientific notation. 6.7 is between 1 and 10. So, **move the decimal point in 67,000 to the left 4 places and multiply by 104** . 67,000 = 6.7104 To write scientific notation in standard form, look at the exponent.

## How do you write 3000000 in scientific notation?

To get to “standard” scientific notation, we move the decimal point so there is only one non-zero digit in front of the decimal point. So, 3,000,000 becomes **3.000,000** . The trailing zeroes are not significant, so 3.000,000 becomes 3 . We moved the decimal point six places, so the exponent is 6 .

## Which of the following could not be expressed in scientific notation?

2.300000 can not be expressed as scientific notation? **4 x 10⁻⁴** is already in scientific notation. 4 x 10⁻⁵ is already in scientific notation. Hence 2.300000 can not be expressed in scientific notation.

## How do you write scientific notation?

A number is written in scientific notation **when a number between 1 and 10 is multiplied by a power of 10**. For example, 650,000,000 can be written in scientific notation as 6.5 ✕ 10^8.

## How do you solve scientific notation?

To convert to scientific notation, **start by moving the decimal place in the number until you have a coefficient between 1 and 10**; here it is 3.45. The number of places to the left that you had to move the decimal point is the exponent. Here, we had to move the decimal 4 places to the right, so the exponent is -4.

## How do you know if a number is not written in scientific notation?

**Scientific notation review**

- A number is written in scientific notation when there is a number greater than or equal to 1 but less than 10 multiplied by a power of 10.
- If we have a number greater than 10, we move the decimal point to the left until we have a number between 1 and 10.

## How do you write 12 in scientific notation?

Incorrect. Almost correct, but now you have to convert the coefficient 12 into scientific notation. 12 is greater than 10 and scientific notation requires this number to be greater than or equal to 1 and less than 10. The correct answer is **1.2 x 10 ^{–}^{4}**.

## How do you write 1.5 in scientific notation?

The number 10 is called the base because it is this number that is raised to the power n. Although a base number may have values other than 10, the base number in scientific notation is always 10.

1.5: Scientific Notation – Writing Large and Small Numbers.

Explanation | Answer | |
---|---|---|

d | Because the decimal point was moved four places to the left, n = 4. | 1.2378×104 |

## How do you find volume in scientific notation?

Quote from the video:

*You have to move the decimal over 4 places to be able to get five point two eight and then of course you have to write times 10 to the 4 to maintain the same out of five.*

## How do you find density in scientific notation?

The Density Calculator uses the formula **p=m/V**, or density (p) is equal to mass (m) divided by volume (V). The calculator can use any two of the values to calculate the third. Density is defined as mass per unit volume.

## How do I find the volume?

Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is **length × width × height**.

## How do you write a number in decimal notation without using exponents?

Quote from the video:

*This example if we multiply a number by 10 raised to a negative power the number is going to get smaller and therefore the decimal must move to the left. So we'll start with seven point eight five.*

## How do you write 710000 in scientific notation?

710,000 (seven hundred ten thousand) is an even six-digits composite number following 709999 and preceding 710001. In scientific notation, it is written as **7.1 × 10 ^{5}**.

## How do you convert a decimal to a power?

Explanation: To convert a decimal into scientific notation, **move the decimal point until you get to the left of the first non-zero integer**. The number of places the decimal point moves is the power of the exponent, because each movement represents a “power of 10”.

## How do you write a decimal in scientific notation?

Quote from the video:

*Example of writing a decimal in scientific notation. So here's our decimal here and don't forget to write in scientific notation. We want to get a number greater than or equal to one but less than 10.*

## How do you write 0.00001 in scientific notation?

Hence, the scientific notation of \[0.00001\] is **$ 1 \times {10^{ – 5}} $** . So, the correct answer is “ $ 1 \times {10^{ – 5}} $ ”. Note: Scientific notation is a way of expressing numbers that are too large or too small to be conveniently written in decimal form.

## How do you write 2.0 in scientific notation?

If you wanted to express this sum in scientific notation, you’d write **2.0 x 10 ^{3}**. Here’s how we made that conversion. When you use scientific notation, what you’re really doing is taking a small number (i.e., 2.0) and multiplying it by a specific exponent of 10 (i.e., 10

^{3}).
