3. Simplify \[ \frac{p^{5}}{p^{-7}} \] Write your answer with a positive exponent only.

Step 1 ：Given the expression \(\frac{p^{5}}{p^{-7}}\)

Step 2 ：We can simplify this by using the rule of exponents which states that when dividing like bases, you subtract the exponents.

Step 3 ：So, we subtract -7 from 5 to get the simplified expression.

Step 4 ：The simplified expression is \(p^{12}\)

Step 5 ：\(\boxed{p^{12}}\) is the final answer.
