Question 77488
{{{sqrt(x/5) + sqrt(20x) - sqrt(45x/4)}}}
{{{sqrt(x)*(sqrt(1/5) + sqrt(20) - sqrt(45/4))}}}
{{{sqrt(x)*(sqrt(1/5) + 2*sqrt(5) - (3/2)*sqrt(5))}}}
{{{sqrt(x)*(sqrt(1/5) + (1/2)*sqrt(5))}}}
{{{sqrt(x)*((2 + 5) / (2*sqrt(5)))}}}
{{{sqrt(x)*(7 / (2*sqrt(5)))}}}
{{{7*sqrt(5x) / 10}}} answer (I hope)
