Mathematics
1 answer:
timofeeve [1]4 years ago

Answer:

  see below

Step-by-step explanation:

The applicable rules of exponents are ...

  • (a^b)(a^c) = a^(b+c)
  • a^(-b) = 1/a^b

Using these to simplify your expression, you get ...

\dfrac{-9x^{-1}y^{-9}}{-15x^{5}y^{-3}}=\dfrac{-9}{-15}x^{-1-5}y^{-9-(-3)}\\\\=\dfrac{3}{5}x^{-6}y^{-6}=\dfrac{3}{5x^6y^6}
