Main Ideas:To divide power having the same base, subtract exponents.

Problem #1: 5^4x5^8 / 5^7

Solution for Problem # 1: 5^4x5^8 = 5^12 **Add Exponents** 5^12/5^7= 12-7 = 5^5 **Subtract numerator and denominator exponents** Problem #2: 5^9/5^7

Solution for Problem #2 :5^9/5^7 = 9-7 =52 Subtract Exponents
