Question

EXERCISE 1.2
(1) Find the square root of the following
complex numbers
(1)-8–6 ii) 7+24i iii) 1+4/3 i
iv) 3+2 V10i v) 2(1-13i)​

Answer 1

Step-by-step explanation:

1) -8-6 = -14

square root = ✓(-14)^2

= 14

2) 7+24i

square root = ✓ (7)^2 + (24)^2

= ✓ 49 + 576

= ✓625

= 25

3) 1+4/3 I

square root = ✓ (1)^2+ (4/3)^2

= ✓1+16/9

= ✓ 25/9

= 5/3

5) 3+2 = 5

square root = ✓(5)^2

= 5

6) 2(1-13i) = 2-26i

square root = ✓ (2)^2+(-26)^2

= ✓ 4+676

= ✓ 680
