HELPPPPPPPPP i have the most trouble with math what’s the answer??

Answer 1

Answer:

$\frac{9+\sqrt{14} }{9+\sqrt{14}}$

Step-by-step explanation:

The given expression is $\frac{5-\sqrt{7} }{9-\sqrt{14} }$.

To rationalize this expression, we need to multiply the numerator and the denominator by the conjugate of  $9-\sqrt{14}$ which is $9-\sqrt{14}$,

Therefore we need to multiply by;

$\frac{9+\sqrt{14} }{9+\sqrt{14}}$

The third option is correct
