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}}

or

\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}
