Answer:
2^12
Step-by-step explanation:
I know that 128 is 32 x 4, so 128 is 2^5 x 2 x 2 = 2^7. Thus,
128 x 32 = 2^5 x 2^7.
The last step is to realize that if two factors have the same base (in this case, both bases are 2), then you can add the exponents:
2^5 x 2^7 = 2^5+7= 2^12.
And that is in exponential form. So the final answer is
128 x 32 = 2^12
