Answer 1

To simplify the expression \( \frac{5^3}{5^{-2}} \), we can use the properties of exponents. According to the rules of exponents, when you divide with the same base, you subtract the exponents:

\[
\frac{5^3}{5^{-2}} = 5^{3 - (-2)} = 5^{3 + 2} = 5^5
\]

Now we will evaluate the responses to see which are equivalent to \( 5^5 \):

1. **55** - This is not equivalent to \( 5^5 \).
2. **5 to the th power5** - This is equivalent to \( 5^5 \).
3. **3125** - \( 5^5 = 3125 \). So this is equivalent.
4. **15 over 1** - This simplifies to 15, which is not equivalent to \( 5^5 \).
5. **5^-1** - This is not equivalent since it represents \( \frac{1}{5} \).
6. **5 to the th power1** - This is \( 5^1 \), which is not equivalent to \( 5^5 \).
7. **5** - This is not equivalent as it represents \( 5^1 \).

The expressions that are equivalent to \( \frac{5^3}{5^{-2}} \) are:

- **5 to the th power5**
- **3125**
