What is 256 in exponential form?

4^2 * 4^2.

-John

4²*4²=16*16 =256

4² x 4² = 16 x 16 = 256
OPTION 3.

4^2 X 4^2

256
= 16^2
= 4^4 (4^2 x 4^2)
(answer 3)

its 3.

this is because it is also the squareroot of 16.

16 can also be wirtten as 4^2.
therefore 16*16 = 4^2 * 4^2

hope this helps.

You know. Since there are only four answers, you could just multiply each one out and see what you get. The one that gives you 256 will be your answer.

3. 4^2 × 4^2
