Question

How would you evaluate `(5.7×106 kg) × (6.3×10−2 m/s2)` and express the answer in scientific notation?

Answer 1

`3.591xx10^5N`

Explanation:

Probably there is a formatting issue with the question. I will attempt to be a mind-reader and restate as following

Evaluate `(5.7xx10^6kg)xx(6.3xx10^-2ms^-2)` and express the answer in scientific notation

`(5.7xx10^6kg)xx(6.3xx10^-2ms^-2)`, Multiplying numbers and treating powers of `10` separately we obtain

`(5.7xx6.3xx10^6xx10^-2)(kgms^-2)`
`(35.91xx10^6xx10^-2))(kgms^-2)`,
we know that `(kgms^-2)` looks like mass times acceleration and has symbol `"N` for Force.
Also shifting the decimal by one place to the left to represent in scientific notation
`(3.591xx10^1xx10^6xx10^-2)(N)`, adding powers of 10
`(3.591xx10^(1+6-2))N`
`3.591xx10^5N`
