Question 78048
If your problem looks like this 

{{{sqrt(4/5)}}} then

{{{sqrt(4)/sqrt(5)}}} We can rewrite the problem as this using this property: {{{sqrt(x/y)=sqrt(x)/sqrt(y)}}} 


Since 4 is a perfect square, we can take the square root of 4 to get


{{{2/sqrt(5)}}} So this is our simplified answer.
