To solve this, we should follow order of operations. To start, we should multiply the values inside of the parentheses.

(34.6785*5.39)+435.12
186.917115+435.12

Now, we should add the 2 values we are left with together.

186.917115
<u>+435.120000
</u><u />622.037115

Using the math above, we can see that this expression is equal to 622.037115.
