Which expression is equivalent to 4x4x4x4x4x4x4x4?

Question

a. 4 x 8
b. 8^4
c. 8x8
d. 4^8

I think D.

Answer 1

D is correct.

If you do the math for both, you can see they both get the answer of 65,536.

4 x 4 x 4 x 4 = 256
4 x 4 x 4 x 4 = 256
256 x 256 = 65,536

4^8 = 4 x 4 x 4 x 4 x 4 x 4 x 4 x 4 = 65,536

So, D is correct.

I hope this helps! :)

Answer 2

Also, if you do the math for each answer, they don't equal 65,536 when solved.

A. 4 x 8 = 12 -(This one is not the answer because of the answer of 12.)

B. 8^4 = 8 x 8 x 8 x 8 = 4,096 -(This is also not the answer because of 4,096.)

C. 8 x 8 = 64 -(Similar to A, but this is not the answer to the problem.)

So again, D is correct because is equals 65,536 when solved.

I hope this helps you more! :)
