## KrystaRenee What is the value of 10x^–3y^–1 for x = –1 and y = –3? 10(3)^-4 30 10/81 3 1/3 one year ago one year ago

1. Kitt020912

plug the x and the y into the equation $10(-1)^{-3}-3^{-1}$

2. Kitt020912

and solve (:

3. Kitt020912

$-10^{-3}(-3^{-1})$

4. Kitt020912

so $-10\times-3$ and then everytime you multiply numbers, you always add the exponents. so $-3+(-1)$
