Question

3m2 + 2p2 − 15 when m = 3 and p = 10

Answer 1

212 is your answer, Im pretty sure on this one. 

Answer 2

3*3= 9 and 2*10= 20 since the are to the power of 2 u need to multiply the number twice like 20*20 and 9*9. 20*20= 400 and 9*9= 81. change your equation to fit the new numbers in. 81 +  400 - 15 = 466. 466 is your answer.
