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)|)))#
