Answer 1

To rewrite the expression \( \frac{7^3}{25^{-4}} \) with only positive exponents, we'll use the property of negative exponents, which states that \( a^{-b} = \frac{1}{a^b} \).

1. Rewrite \( 25^{-4} \):
\[
25^{-4} = \frac{1}{25^4}
\]

2. Substitute it back into the original expression:
\[
\frac{7^3}{25^{-4}} = 7^3 \cdot 25^4
\]

Now, we can see that this expression \( 7^3 \cdot 25^4 \) is equivalent to the option:

**73⋅254**

So, the correct answer is:
**7 cubed times 25 superscript 4 baseline.**
