Question

prove that..... (1+i)*200/(1-i) *200=1​

Answer 1

Multiply numerator and denominator by denominator itself ie rationalise the inside term and multiply.

U will get 2/-2i raise to power 200

Which 1/-i ^ 200.

Now again multiply Nr and Dr by i we get i^200 and if any power of iota is a multiple of 4.. The answer is 1

Therefore the answer is (one) 1 !
