Which expression is equal to 5/(sqrt)11?

horrorfan [7]

Answer:

Option A is correct

the expression is equal to $\frac{5}{ \sqrt{11}}$ is $\frac{5\sqrt{11}} {11}$

Explanation:

Given expression is, $\frac{5}{ \sqrt{11}}$

Multiply and divide by the denominator by $\sqrt{11}$ in the given expression, we have,

$\frac{5}{\sqrt{11}} \times \frac{\sqrt{11}} { \sqrt{11}}$

$\frac{5 \cdot \sqrt{11}} {\sqrt{11} \cdot \sqrt{11}}$

use : $\sqrt{a}\cdot\sqrt{a}=(\sqrt{a} )^2 = a$

then;

$\frac{5\sqrt{11}} { (\sqrt{11})^2} =\frac{5\sqrt{11}} {11}$

Therefore, the expression is equal to $\frac{5}{ \sqrt{11}}$ is, $\frac{5\sqrt{11}} {11}$
