Solution: Given (1+ i)2n = (1 - i)2n [(1+i)/(1-i)]2n = 1 Multiply numerator and denominator with (1+i) We get [(1+i)(1+i)/(1-i)(1+i)]2n = 1... View Article
Solution: Given [(1+i)/(1-i)]n = 1 Multiply numerator and denominator with (1+i) We get [(1+i)(1+i)/(1-i)(1+i)]n = 1 [(1+2i-1)/(1-i2)]n = 1... View Article
Solution: Given (x-1)3+8 = 0 (x-1)3= -8 Taking cube root on both sides (x-1) = 2(-1)1/3 (x-1)/-2 = 1 or (x-1)/-2 = w , (x-1)/-2 = w2 So x =... View Article
