What is the simplified form of the expression? 5(14-2)^2/2 A. 60 B. 30 C. 72 D. 360

What do you believe the correct answer is?

OpenStudy (anonymous):

Well first it'd be good to figure out what the 5(14-2)^2 bit is, lemme calculate that real quick.

OpenStudy (anonymous):

I got 120. Is that right? With that, it's now 120/2. Simplified, 60/1.

OpenStudy (anonymous):

So is it A?

OpenStudy (anonymous):

Incorrect. Remember PEMDAS ;)

OpenStudy (anonymous):

oooh. okay, let me do that again then.

OpenStudy (anonymous):

I see you may have distributed first

OpenStudy (anonymous):

Following pemdas, you'd do parenthesis first so "14-2" then exponent, so 12^2, which is 144. Then multiply by 5, you get 720.
