Is 2^7 the same as 2 x 7? Why or why not?

Answers

Answer 1

Answer:

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.

Answer 2

Answer:

Answer:

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

Step-by-step 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

f(-1) = 8
