Answer:Let z = x + iy where x and y are real and i = √-1. ... denoted by mod(z) or |z| or |x + iy|, is defined as |z|[or mod z or |x + iy|] = + √x2+y2 ,where a = Re(z), b = Im(z) ... (ii) If z = -6 + 8i then |z| = √(−6)2+82 = √100 = 10. ... (vii) If z = 3 - √7i then |z| = √32+(−√7)2 =√9+7 = √16 = 4.
