Question

2) Rationalize the denominator: 3
(2V5 - 314)​

Answer 1

Answer:

$\frac{3}{(2 \sqrt{5} - 314) } \times \frac{(2 \sqrt{5} + 314 )}{(2 \sqrt{5} + 314)} \\ = \frac{3(2 \sqrt{5} + 314)}{(2 \sqrt{5} {)}^{2} - (314 {)}^{2} } \\ = \frac{3(2 \sqrt{5} + 314) }{20 - 98596} \\ = \frac{3(2 \sqrt{5} + 314)}{98576} \\ answer$
