how do i do this and what is the answer

Answer:
[tex]4x^6[/tex]
Step-by-step explanation:
Let's write it as a fraction:
[tex]\frac{4x^3y}{x^{-3}y}[/tex]
Division of exponents rule: [tex]\frac{a^x}{a^b}= a^{x-b}[/tex]
Use this formula for x and y
[tex]\frac{x^3}{x^{-3}} = x^{3- (-3)} = x^6[/tex]
[tex]\frac{y^1}{y^1} = y^{1-1} = y^0 = 1[/tex]
Now use these answers in the fraction
[tex]4x^6*1 = 4x^6[/tex]
