Question

1/2√5-3 rationalise the denominator

Answer 1

$\frac{1}{2 \sqrt{5} - 3} \times \frac{2 \sqrt{5} + 3}{2 \sqrt{5} + 3}$

$\frac{2 \sqrt{5} + 3 }{20 - 9}$

$\frac{2 \sqrt{5} + 3}{11}$

please mark as branliest answer

Answer 2

Answer:

$\boxed{\frac {\sqrt [2]{5} + 3}{11}}$

Step-by-step explanation:

$\implies\large\mathtt{\frac {1}{\sqrt [2]{5} - 3}}$

$\implies\large\mathtt{\frac {1}{\sqrt [2]{5} - 3} \times \frac {\sqrt [2]{5} + 3}{\sqrt [2]{5} + 3}}$

$\implies\large\mathtt{\frac {\sqrt [2]{5} + 3}{(\sqrt [2]{5})^2 - (3)^2}}$

$\implies\large\mathtt{\frac {\sqrt [2]{5} + 3}{20-9}}$

$\implies\large\mathtt{\frac {\sqrt [2]{5} + 3}{11}}$
