$f (3.1) = \frac{\sqrt{x - 2}}{x^{2} - 2}$

Step 1

Replace the variable $x$ with $3.1$ in the expression.

$f (3.1) = \frac{\sqrt{(3.1) - 2}}{{(3.1)}^{2} - 2}$

Step 2

Step 2.2.1

Raise $3.1$ to the power of $2$ .

$f (3.1) = \frac{\sqrt{1.1}}{9.61 - 2}$

Step 2.2.2

Subtract $2$ from $9.61$ .

$f (3.1) = \frac{\sqrt{1.1}}{7.61}$

Step 2.3

Evaluate the root.

$f (3.1) = \frac{1.04880884}{7.61}$

Step 2.4

Divide $1.04880884$ by $7.61$ .

$f (3.1) = 0.13781982$

Step 2.5

The final answer is $0.13781982$ .
