How would i solve for this problems?
also what is the answer(s)
5.)Which answers are equal to the expression √16 x √25
a.√41
b.√16 x 25
c.(16 x 25)^1/2
d.20
e.400
f.√25 x √16

clearly
c) d) and f) 
the computer test says that c,d,f are wrong

it said Remember, Also, the radical sign is the same as an exponent of 1/2 and Make sure that each answer you select has the same value as the expression in the box.

after reviewing the book i found the answer, which is b,c,d,f are all equal to the expression √16 x √25

b) is not a correct choice
√16 x 25 = 4x25 = 100
It would be correct if you had said
√(16 x 25)
the way you typed it, I am 100% sure it is c) d) and f)
