SOLUTION
------------------------------------------------------------
2. Explain why (-1)^n= 1 for any even number n.
(-1)^n = (-1)x(-1)x(-1) ... x(-1)
(-1)x(-1) = +1 , when n=3 , which is odd
We can say that whenever n is even
(-1)^n = 1 , because [ (-)x(-) = + ]
beacase when n for any even number
( - 1)^n = ( - 1)² = 1
