Simplifying (x3)4(x2)5(x6)5\frac{(x^3)^4(x^{-2})^5}{(x^6)^5} Using Several Exponent Properties

To simplify the rational expression (x3)4(x2)5(x6)5\frac{(x^3)^4(x^{-2})^5}{(x^6)^5}, apply the Power Property, Product Property, and Quotient Property in sequence. First, use the Power Property (am)n=amn(a^m)^n = a^{m \cdot n} on the numerator and the denominator: (x3)4=x12(x^3)^4 = x^{12}, (x2)5=x10(x^{-2})^5 = x^{-10}, and (x6)5=x30(x^6)^5 = x^{30}. The expression becomes (x12)(x10)x30\frac{(x^{12})(x^{-10})}{x^{30}}. Next, add the exponents in the numerator: x12x10=x2x^{12} \cdot x^{-10} = x^2. The expression simplifies to x2x30\frac{x^2}{x^{30}}. Finally, use the Quotient Property aman=1anm\frac{a^m}{a^n} = \frac{1}{a^{n-m}} to subtract the exponents: 1x302=1x28\frac{1}{x^{30-2}} = \frac{1}{x^{28}}.
