Question

How do you evaluate the expression `n^4` when n=7 and when n= 0.4?

Answer 1

When `n=7`, `n^4=7^4=7*7*7*7=2401.`
Similarly, when `n=0.4`, `n^4=(0.4)^4=(0.4)*(0.4)*(0.4)*(0.4)=0.0256.`

Explanation:

When `n=7`, `n^4=7^4=7*7*7*7=2401`
Similarly, when `n=0.4`, `n^4=(0.4)^4=(0.4)*(0.4)*(0.4)*(0.4)=0.0256.`
