Since you have an x in the denominator, rationalizing will not simplify properly: $(5sqrt(7x))/(14x)$

multiply by $sqrt(28x)/sqrt(28x)=1$

$5/sqrt(28x)xxsqrt(28x)/sqrt(28x)=(5sqrt(28x))/(28x)$

$=5sqrt(2^2*7x)/(28x)=(5*2*sqrt(7x))/28x=(5sqrt(7x))/(14x)$

How do you rationalize the denominator and simplify 5/sqrt(28x)5/sqrt(28x)?
