Question

Need help, I'm stuck on this​

Answer 1

The answer is 729/64.

Explanation:

I would first simplify the equation.

In the denominator, you can get rid of b^0 because that just equals 1.

For the a's in the numerator and denominator, you have to flip them so the exponents can be positive.

Equation:
`((3ab^2)/(2a^3))^2`

Now, you can subtract a and a^3. This would be 1/a^2.

Equation:
`((3b^2)/(2a^2))^2`

Now, you can square the whole equation.

Equation:
`(9b^4)/(4a^4)`

This is the simplified equation. Now you can plug in -2 and -3.

Equation:
`(9(-3)^4)/(4(-2)^4)`

Equation:
`(9(81))/(4(16))`

Equation: 729/64
