#### Answer

$196$

#### Work Step by Step

We start with the given expression: $(2a+2b)^2$ We plug in values for $a$ and $b$: $(2(3)+2(4))^2$ The order of operations states that first we perform operations inside grouping symbols, such as parentheses, brackets, and fraction bars. Then, we simplify powers. Then, we multiply and divide from left to right. Finally, we add and subtract from left to right. We use these rules to simplify the expression. We start by following the order of operations to simplify inside the parentheses: First, we multiply from left to right: $(6+2(4))^2=(6+8)^2$ Next, we add inside parentheses: $14^2$ Finally, we simplify powers: $196$
