Answer
x = -6
y = 4
Explanation
We are asked to determine the values of x and y in the expressions
[tex]\begin{gathered} g^x+h^{-3}=\frac{1}{g^6}+\frac{1}{h^3} \\ =g^{-6}+h^{-3} \end{gathered}[/tex]
Comparing, we can easily see that x = -6
[tex]\begin{gathered} b^4c^{-7}=\frac{b^y}{c^7} \\ =\frac{b^4}{c^7} \end{gathered}[/tex]
We can see too that y = 4
Hope this Helps!!!
