Explanation:
Given,
(2+sqrt(3))/(5-sqrt(3))
Multiply the numerator and denominator by the conjugate of the denominator.
=(2+sqrt(3))/(5-sqrt(3))*((5+sqrt(3))/(5+sqrt(3)))
Simplify.
=(10+2sqrt(3)+5sqrt(3)+3)/(25-3)
=color(green)(|bar(ul(color(white)(a/a)color(black)((7sqrt(3)+13)/22)color(white)(a/a)|)))
