Question

rationalisation 3+ root7 / 3 - 4 root 7

Answer 1

Answer:

-$\frac{37+15\sqrt{7}}{103}$

Step-by-step explanation:

$\frac{3+\sqrt{7} }{3-4\sqrt{7} }$ × $\frac{3+4\sqrt{7} }{3+4\sqrt{7} }$ = $\frac{(3+\sqrt{7})(3+4\sqrt{7})}{(3-4\sqrt{7})(3+4\sqrt{7})}$ = $\frac{9+12\sqrt{7}+3\sqrt{7}+28}{9-112}$ = $\frac{-37-15\sqrt{7}}{103}$ OR -$\frac{37+15\sqrt{7}}{103}$
