Simplify the expression.

Tamiku [17]

Answer:

$\boxed{=144--> C.}$

Step-by-step explanation:

<u><em>You had to used pemdas stands for: p-parenthesis, e-exponents, m-multiply, d-divide, a-add, and s-subtract that came from left to right.</em></u>

First you calculate with parenthesis first.

$(13-1)^2/2$

$12^2/2$

Then you calculate with exponents.

$12^2=12*12=144$

$144/2$

Next, divide from left to right.

$144/2=72$

$144/72=2$

$72*2=144$

$2*72=144$

$=72$

$2*72$

Finally, multiply from left to right.

$72*2=144$

$12*12=144$

Final answer: $\boxed{=144}$

Hope this helps!
