I did like this: Let A = (1 + i)^(52) A = (√2)^(52) × [cis(π/4)]^(52) A = 2^(26) × cis(52π/4) A = 2^(26) × cis(13π) Now cis(13π) = - 1 A = - [2^(26)] A = - [4^(13)] So the answer is - [4^(13)] The answer is not (-4)^(13). Please check it once.

@@ankithsai1 yes this is also correct way of doing.what you gave is an elaborated version for subjective papers. I have given a short trick to be used for competitive exams.

PQ + 1 = Q QR + 1 = R Substitute the value of Q R(PQ + 1) + 1 = R PQR + R + 1 = R PQR = - 1

x = 97 + 56√3 x = (7+4√3)² √x = 7 + 4√3 √x = (√3 + 2)² x^(1/4) = 2 + √3 Now 1/x^(1/4) = 1/(2+√3) = (2-√3) So (2+√3) + (2-√3) = 4
