Question

How do you write the answer in scientific notation given `(7.2times10^-3)^3`?

Answer 1

`3.73248^("-"7)`

Explanation:

First apply the exponent to all terms
`7.2^3xx(10^("-"3))^3`

Simplify
`373.248xx10^("-"9)`

Write the number in scientific notation
`(3.73248xx10^2)xx10^("-"9)`

Combine the powers of `10`
`3.73248xx10^(2-9)=3.73248^("-"7)`
