Question

Which of the following values for m proves that 2m + 2m is not equivalent to 4m2?

m = 0
m = 1
m = 2

Answer 1

m=0 i am not sure it is right 

Answer 2

When m=0 ,

2m+2m=2(0)+2(0)= 0

$4m^{2}.=4(0^{2})=0$

When m=1 ,

2m+2m=2(1)+2(1)=2+2=4.

$4m^{2}. =4(1)^{2}.=4.$

When m=2

2m+2m=2(2)+2(2)=4+4=8.

$4m^{2}.=4(2)^{2}.=4(4)=16.$

Both expressions are not equivalent when m=2.
