even root property , find real solutions ... w^2+49=0 ; find imaginary solution.. w^2=-225; sqrt(16^n)
--------------------
w^2+49 = 0
(w+7i)(w-7i) = 0
w = -7i or w = 7i
========================
w^2 = -225
w^2 + 225 = 0
(w+15i)(w-15i) = 0
w = -15i or w = 15i
========================
sqrt(16^n) = sqrt(4^(2n))
= 4^n
===========================
