Chapter 4 - Polynomials - 4.2 Negative Exponents and Scientific Notations - 4.2 Exercise Set: 8

Option (b)

Work Step by Step

Use the rule $\left(\frac{a}{b}\right)^m=\frac{a^m}{b^m}$ to obtain: $=\dfrac{(x^{-3})^{-3}}{(y^{-2})^{-3}}$ Use the rule $(a^m)^n=a^{mn}$ $=\dfrac{x^{-3(-3)}}{y^{-2(-3)}} \\=\dfrac{x^9}{y^6}$ Thus, the answer is Option (b).
