Question

What is the number written in standard notation?

5 x 10 ^3
A. 500
B. 5,000
C. 50 ^3
D. 150

Answer 1

5000 is the number written in standard notation.

i.e.
`5* \:10^3=5000`

Explanation:

Considering the number written in scientific notation

`5\:* \:10\:^3`

Lets convert it into the standard notation

`5\:* \:10\:^3`

The positive exponent i.e. 3 indicates a large number.

First calculating exponents

`10\:^3=10* \:10* \:10=1000`

so

`5\:* \:\:10\:^3=5* 10* 10* 10\:`

`=5* \:1000`

`=5000`

Therefore, 5000 is the number written in standard notation.

i.e.
`5* \:10^3=5000`

Answer 2

option B

Explanation:

To find the number which is written in the standard form,
`5 * {10}^(3)`

We expand
`{10}^(3)` and multiply by 5 to get

`= 5 * (10 * 10 * 10)`

`=5* 1000`
