Step 1

Simplify each term.

Tap for more steps...

Step 1.1

Raise $3$ to the power of $2$ .

$f (3) = 2 \cdot 9 + 5 \sqrt{3 - 2}$

Step 1.2

Multiply $2$ by $9$ .

$f (3) = 18 + 5 \sqrt{3 - 2}$

Step 1.3

Subtract $2$ from $3$ .

$f (3) = 18 + 5 \sqrt{1}$

Step 1.4

Any root of $1$ is $1$ .

$f (3) = 18 + 5 \cdot 1$

Step 1.5

Multiply $5$ by $1$ .

$f (3) = 18 + 5$

$f (3) = 18 + 5$

Step 2

Add $18$ and $5$ .

$f (3) = 23$
