$176.3632616 \ldots$ or $176.36$

#### Explanation:

Assuming you mean:

$3 \sqrt{12} + 4 \sqrt{18}$,

Evaluate by first finding the square roots:

$3 \left(3.464101615 \ldots\right) + 4 \left(4.242640687 \ldots\right)$

Then mulitply:

$\left(10.39230485 \ldots\right) + \left(16.97056275 \ldots\right)$

$= 176.3632616 \ldots$
I like to round up, to $176.36$, in this case.
