Answer 1

Answer:

b 15 - 4i sqrt(2)

Step-by-step explanation:

15 - sqrt (-32)

15 - sqrt(-1) sqrt(32)

15 - ±i sqrt(16) sqrt(2)

15 - ±4i sqrt(2)

Taking the principal square root

15 - 4i sqrt( 2)

Answer 2

15 - √-32

Rewrite √-32 as √-1 * √32

√-1 = i

Now you have 15 - i * √32

Rewrite √32 as √(4^2 * 2)

Pull terms out from under the radical:

15 - i * 4√2

Multiply i by 4 to get final answer of 15 - 4i√2
