Question 498856
Presumably you are required to solve for the variable a.
{{{3+(sqrt(3+3)) = 9}}} Simplify.
{{{6+sqt(3)a = 9}}} Subtract 6 from both sides.
{{{sqrt(3)a = 3}}} Divide both sides by {{{sqrt(3)}}}
{{{a = 3/sqrt(3)}}} Rationalise the denominator.
{{{a = 3sqrt(3)/(sqrt(3)*sqrt(3))}}} Simplify.
{{{a = 3sqrt(3)/3}}} Cancel the 3's.
{{{highlight(a = sqrt(3))}}}
