Answer 1

(1632)*(4.0*10^ 4) = 6.528*10^7

Answer 2

Answer:

Answer of the given multiplication is $6.5\times 10^{7}$

Explanation:

For multiplication or division of multiple digits, the final answer should contain equal number of significant figure to that digit containing least number of significant figure.

1632 has four significant figures and $4.0\times 10^{4}$ has two significant figures. Hence $4.0\times 10^{4}$ has least number of significant figures.

So answer should contain two significant figures.

Hence $(1632)(4.0\times 10^{4})$ = $6.5\times 10^{7}$
