Answer:

No, 2^7 is not the same thing as 2 x 7

Explanation:

When you are doing 2 x 7 you multiply 7 by 2. For 2^7, you multiply 2 by 2 7 times.

2 x 7 = 2 x 7

2^7 = 2 x 2 x 2 x 2 x 2 x 2 x 2

Answer: No

Explanation: In the first problem, 2 is a base and 7 is an exponent.

The 7 that is raised up means we multiply our base together seven times.

This means the same thing as 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 or 128.

On the other hand, 2 × 7 is 14.

It can also be thought of as 2 + 2 + 2 + 2 + 2 + 2 + 2 or 14.
