Question

Evaluate expression.

Answer 1

\[2i^{124}-3i^{10}\]

Answer 2

What does i =?

Answer 3

it stands for...\[\sqrt{-1}\]

Answer 4

Sorry I don't do Square Roots. :(

Answer 5

Darn :/

Answer 6

first you must know that i^2=-1...so, you've got 2i^124=2*(i^2)^62=2*62=124
then 3*i^10=3*(i^2)^5=3*(-1)=-3 so the result is 124-(-3)=127

Answer 7

oh sorry I made the mistake in the begining 2*(i^2)^62=2*1=2 the other part is fine so the result is2-(-3)=5 sorry if you got confused :D

Answer 8

Oh well thanks
