the answer is 1/(x-4)^3 because if you see in the equation they gave the same x-4 variable. As three of the same variable are being multiplied it adds the ^3 to the x-4. As (x-4) is all being divided by 1 it creates the solution 1/(x-4)^3. I hope this helps.

you are multiplying 3 algebraic fractions together

[tex]\frac{1}{x-4}[/tex] × [tex]\frac{1}{x-4}[/tex] x [tex]\frac{1}{x-4}[/tex]

multiply the numerators together, that is 1 × 1 × 1 = 1

multiply the denominators together, that is

(x - 4 ) × (x - 4 ) × (x - 4 ) = (x - 4)³

thus the product of the multiplication is

[tex]\frac{1}{(x-4)^{3} }[/tex]
