Answer 2

The value of $\[\frac{1}{\sqrt{7}}\]$ is 0.378.

Step-by-step explanation:

Given:

The value root 7 is equal to 2.646.

To find:

The value of $\[\frac{1}{\sqrt{7}}\]$

On multiplying ${\sqrt{7}}$ on both numerator and denominator,

$\[\begin{align} & \frac{1}{\sqrt{7}}=\frac{1}{\sqrt{7}}\times \frac{\sqrt{7}}{\sqrt{7}} \\ & \frac{1}{\sqrt{7}}=\frac{\sqrt{7}}{7} \\ & \frac{1}{\sqrt{7}}=\frac{2.646}{7} \\ & \frac{1}{\sqrt{7}}=0.378 \\ \end{align}\]$$\[\begin{align} & \frac{1}{\sqrt{7}}=\frac{1}{\sqrt{7}}\times \frac{\sqrt{7}}{\sqrt{7}} \\ & \frac{1}{\sqrt{7}}=\frac{\sqrt{7}}{7} \\ & \frac{1}{\sqrt{7}}=\frac{2.646}{7} \\ & \frac{1}{\sqrt{7}}=0.378 \\ \end{align}\]$            $\frac{1}{\sqrt{7}}=\frac{1}{\sqrt{7}}\times \frac{\sqrt{7}}{\sqrt{7}}$

$& \frac{1}{\sqrt{7}}=\frac{\sqrt{7}}{7}$$& \frac{1}{\sqrt{7}}=\frac{\sqrt{7}}{7} \\ & \frac{1}{\sqrt{7}}=\frac{2.646}{7} \\ & \frac{1}{\sqrt{7}}=0.378$
