Question

Rationalise the denominator. Simplify your answer fully. 22 /√ 15 + 2

Answer 1

Answer: $\frac{22\sqrt{15}-44 }{11}$

Step-by-step explanation:

$\frac{22}{\sqrt{15}+2 } *\frac{\sqrt{15}-2}{\sqrt{15}-2} =\frac{22\sqrt{15}-44 }{(\sqrt{15})^2-(2)^2 } =\frac{22\sqrt{15}-44 }{15-4} =\frac{22\sqrt{15}-44 }{11}$
