Question 242644: i am trying to find the answer to this problem but not sure where to begin...

the aquare root of 13z times the square root of 13z
Answer by Theo(13342) (Show Source): You can put this solution on YOUR website!
sqrt(a) * sqrt(a) = sqrt(a)^2 = a

sqrt(13z) * sqrt(13z) = 13z

square root of any number squared is equal to the number.

sqrt(a) is equivalent to a^(1/2)

a^(1/2) * a^(1/2) = a^(1/2 + 1/2) = a^1 = a

same thing in exponent notation form.
