Why is c correct pleaseee I need helppp!!

C is correct because when multiplying 15 times 15(15^2) you get 225. Then by multiplying 3 times 3 times 3 times 3 times 3 (3^4) you get 81. The next step would be to subtract 225-81 which would leave you with 144. 15^2-3^4= 144. To get the answer of 12^2 you would multiply 12 times 12 which =144. So 144=144.

Step-by-step explanation:

A simple answer would be c=144 and 12^2=144

It is C  because 12 to the power of two equals 144

Step-by-step explanation:

it's C because

15 to the power of 2 equals 225 and 3 to the power of 4 equals 81 so if you substract 225 and 81 that will give you 144.

Best of luck and I hope it helps.
