Answer:

5/2

Step-by-step explanation:

The 5^-3 and 5^6 cancel out to be 5^3. Then the 5^3 cancels out with the 5^2 in the denominator and leaves you with just a 5. The 2^2 makes the 2^3 in the denominator just 2. So, you are left with 5/2! Hope this helps.

Divide. Express the quotient in simplest form.

Scorpion4ik [409]

$( \frac{x^2 - x -12}{2x} )$ ÷ $( \frac{x^2 - 2x - 8}{4x^2} )$

= $( \frac{x^2 - x -12}{2x} )$ × $( \frac{4x^2}{x^2 - 2x - 8} )$

= $\frac{x(x^2 - x -12)}{x^2 - 2x - 8}$

= $\frac{x(x^2 -4x +3x -12)}{x^2 -4x +2x -8}$

= $\frac{x[x(x - 4) +3(x - 4)]}{x(x - 4) +2(x - 4)}$

= $\frac{x(x-4)(x+3)}{(x-4)(x+2)}$

= $\frac{x(x+3)}{(x+2)}$
