Question

A cell phone weighs about 2.8 times 10 Superscript n pounds. Which value of n is most reasonable?

Answer 1

-1

Explanation:

I took the quiz :)

Answer 2

I would say n ≈ -1

a cell phone weighs less than a pound, so the reasonable answer would be n ≈ -1

If you substitute -1 in it will look like this.

`2.8 *10^(-1) =0.28` pounds
