Question

Simplify the following expression
square root sign with -104 in it and square root sign with only a - sign in it. please please can someone help me with this one?

Answer 1

U can use sqrt(ab) = sqrt(a)*sqrt(b)to simplify sqrt(104).
The other seems to be some kind of mistake.

Answer 2

oh i am sorry it is -8

Answer 3

in the second square root

Answer 4

can you work this one step by step for me please so i can see how to do

ok so sorry to bother you

Answer 18

square root of -1 is written as i
so sqrt(-104) = sqrt 104 * i

sqrt 104 = sqrt(4*26) = sqrt4 * sqrt26 = 2 sqrt26

sqrt(-104) = 2i sqrt26
