Answer 1

this is a multiplication question as it requires for you to find the height of \(2.5 \times 10^4\) pennies each with the thickness of \(5.98 \times 10^{-2}\) inch.

you can set up your expression as
\((2.5 \times 10^4) \times (5.98 \times 10^{-2})\)

Answer 2

and then multiply the terms that look similar
\((2.5 \times 5.98) \times (10^4 \times 10^{-2})\)
