[(7) 3] 2/n = (7) 2 ⇒ (7) 6/n = (7) 2 ⇒ 6/n = 2 Since, the bases are same and equating the powers, we get n = 6/2 = 3. This rule means that when we multiply a base raised to a power times the same base to another power, the result is the base raised to the sum of the powers. In a similar way to the product rule, we can simplify an expression such as \(\dfrac{y^m}{y^n}\). If you wanted to move b to the numerator along with 5a^7, you would have to write it as b^-1, to indicate it is a negative exponent, as Sal did. Integral Exponents of a Rational Numbers.
