EXERCISE 1.2
1)
Find the square root of the followin
complex numbers
1)-8-6i
ii) 7+24iii) 1+4 131
iv) 3+2/101 v) 2(1-131)​

Answer 1

for complex numbers we find square root as root of a^2+b^2

1)-8-6i = root (8)^2+(6)2

= root (64+36) = root100 = 10

2) 7+24i = root (7)^2+(24)^2

= root (49+576) = root 625 = 25
