Question

How do you evaluate the expression `n^3` when n=7 and when n= 0.4?

Answer 1

when `n=7` then `n^3=7^3=7*7*7=343`
when `n=0.4` then `n^3=0.4^3=(0.4)(0.4)(0.4)=0.064`

Explanation:

when `n=7` then `n^3=7^3=7*7*7=343`
when `n=0.4` then `n^3=0.4^3=(0.4)(0.4)(0.4)=0.064`

God bless....I hope the explanation is useful.
