Hello, Tim!
I assume those are exponents (indices) . . .
Since we're given an equation, I'm not sure what "simplify" means . . .Q1. Manipulate the following expressions and simplify them using the laws of indices.
$\displaystyle a)\;\;x^2y^{-5}\:=\:x^4y^3$
We have: .$\displaystyle x^2y^{-5} \;=\;x^4y^3$
Divide both sides by $\displaystyle x^2\!:\;\;y^{-5} \;=\;x^2y^3$
Multiply both sides by $\displaystyle y^5\!:\;\;1 \;=\;x^2y^8$
So we have: .$\displaystyle x^2y^8 \;=\;1$
. . I suppose that's "simplified" . . .
