(e^2+2)^2How to solve this problem?
I am really very nervous as I'm going to have my M1 exam tmr but I still cannot understand the concept even though I really try my very very best.....

(a+b)^2 = a^2 + 2ab + b^2
so (e^2 +2)^2 = (e^2)^2 + 2 (e^2)(2) + 2^2 = e^4 + 4e^2 + 4

How to solve this problem?

This is not a problem to solve.

If you want to get the value, use your calculator.
