Could someone help me please!!

Answer:
Option C.
Step-by-step explanation:
The given expression is [tex]\frac{x^{y}}{x^{3}}=x^{6}[/tex]
We have to solve the expression for the value of y.
[tex]x^{y}\times x^{-3}=x^{6}[/tex] [Since [tex]x^{a}\times x^{b}=x^{a+b}[/tex]]
[tex]x^{y-3}=x^{6}[/tex]
y - 3 = 6 [By equating the powers of same base]
y = 6 + 3
y = 9
Therefore, Option C is the answer.
