Question

how can you simplify (3·4)²? now, multiply inside parentheses. (3·4)² = (3·4)(3·4) = · ?

Explanation:

Step1: Expand the squared expression

$(3 \cdot 4)^2 = (3 \cdot 4)(3 \cdot 4)$

Step2: Rearrange factors (commutative property)

$=(3 \cdot 3) \cdot (4 \cdot 4)$

Step3: Multiply inside parentheses first

$=9 \cdot 16$

Answer:

$9 \cdot 16$ (or the final simplified value $144$; the first blank is $9$, the "?" is $16$)
