mathstudent55 · Answer

When you divide a power by a power, and they have the same base, write the same base and subtract the exponents. That's the rule @ajprincess wrote above.
Example:
7^5/7^3
You are dividing two powers, 7^5 and 7^3. They have the same base, 7, so the answer is: write the same base, 7, and the power is the subtraction of the exponents: 5 - 3 = 2. Answer is 7^2 = 7*7 = 49
