evaluate and compare the following expressions. 

sqrt4/25 and sqrt 4 over square root 5

Use your results to make a division and multiplication rule for square roots.

sqrt( 4/25) = sqrt(4) /sqrt(25) =2/5 = 0.4

sqrt(xy)= sqrt(x) * sqrt(y)

sqrt(x/y) =sqrt(x)/sqrt(y)

But sqrt(x+y) is not generally equal to sqrt(x)+sqrt(y)

But sqrt(x-y) is not generally equal to sqrt(x)-sqrt(y)
