Question

Choose a positive number. Using this number as the base, evaluate it when the exponent is 3, 0, and -2. Show all work.

Answer 1

Step by step explaination:
Positive number = 5
When Exponent is 3, it equals: 125
When exponent is 0, it equals: 1
When exponent is -2, it equals: 1/25 or .04

Answer 2

1= 8

2= 1

3= ¼

Explanation:

Let me choose 2. 2 becomes my base.

When the exponent is 3

1. 2³ = 2 * 2 * 2

= 8

When the exponent is 0

2. 2^0.

From the laws of indices. Exponent zero to any number = 1.

Therefore, 2^0 = 1

When the exponent is = -2

3. 2 `² = ¹/2 * 2

= ¼
