Check all that apply.

: 12 is the exponent and tells us how many times we should multiply 5 by itself.

: 12 is the base

: 5 is the base

: 5 is the exponent and tells us how many times we should multiply 12 by itself.

Solution

1. 12 is the exponent and tells us how many times we should multiply 5 by itself – False.

2. 12 is the base – True.

3. 5 is the base – False.

4. 5 is the exponent and tells us how many times we should multiply 12 by itself – True.

Answer:

1. 12 is the base – True.

2. 5 is the exponent and tells us how many times we should multiply 12 by itself – True.

Question

2. If $\sqrt[n]{a} = r$, then which of the following are true statements? Check all that apply.

$$\begin{array}{l} a^r = n \\ a^{\frac{1}{n}} = r \\ n^{\frac{1}{r}} = a \\ r^n = a \\ \end{array}$$

Solution

1. $a^r = n$ – False.

2. $a^{\frac{1}{n}} = r$ – True.

3. $n^{\frac{1}{r}} = a$ – False.

4. $r^n = a$ – True.

Answer:

1. $a^{\frac{1}{n}} = r$ – True.

2. $r^n = a$ – True.
