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)
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
