Answer:
±16
The principle value is 16
Step-by-step explanation:
sqrt(8) * sqrt(32)
We know that sqrt(a) sqrt(b) = sqrt(ab)
sqrt(8*32)
sqrt(256)
sqrt(16*16)
±16
The principle value is 16

To evaluate the answer of Harry:
8-(2+5)8-(2+5)
= -55
To evaluate the answer of Terry:
8-2+58-2+5
= 66
HH = -55
TT = 66
H-TH-T
5-65-5
= -65
