Simplify<br> 7^2x^-3y/49x^-3y^-2

olya-2409 [2.1K]

$\frac{7^2x^{-3}}{49x^{-3} y^{-2}} \\ \\ \frac{49x^{-3}y}{49x^{-3}y^{-2}} \\ \\ \frac{49x^{-3}y}{49x^{-3} \times \frac{1}{y^2} } \\ \\ \frac{49x^{-3}y}{ \frac{49x^{-3}}{y^2} } \\ \\ 49x^{-3} y \times \frac{y^2}{49x^{-3}} \\ \\ \frac{x^{-3}}{x^{-3}} yy^2 \\ \\ 1 \times yy^2 \\ \\ yy^2 \\ \\ y^3 \\ \\$

The answer is: y^3.
