Check the picture below.
so, hmmm notice, since i² = -1 and i⁴ = 1, whenever the exponent is only divisible by 2, the value will be -1, and whenever the exponent is divisible by 4, we end up with a +1, so every subsequent even exponent is simply cancelling the previous value, if we take that to the even value of 100, which has 50 pairs of those, we end up with, yeap, you guessed it, 0.
Your question is:
Then, the above formula equate:
Factor out 8 from the numerator we get:
Factorization of the denominator:
Simplifying the numerator and the denominator by (u-9) we get:
