(-4p)^2 please help me simplify

jimthompson5910 (jim_thompson5910):

(-4p)^2 (-4)^2*(p)^2 what's next?

OpenStudy (anonymous):

not sure

jimthompson5910 (jim_thompson5910):

(-4)^2 = ???

OpenStudy (anonymous):

(p)^2

jimthompson5910 (jim_thompson5910):

no, what is -4 squared?

jimthompson5910 (jim_thompson5910):

ie what is -4 times -4

OpenStudy (anonymous):

0

jimthompson5910 (jim_thompson5910):

4 times 4 = ???

OpenStudy (anonymous):

16

jimthompson5910 (jim_thompson5910):

so -4 times -4 = 16 as well since the two negatives cancel out

jimthompson5910 (jim_thompson5910):

so \[\Large (-4)^2 = 16\]

jimthompson5910 (jim_thompson5910):

which means the answer is \[\Large 16p^2\]
