Im
which shows the following expression after the negative exponents have been eliminated? a^ 3 b^ -2 ab^ -4 ,a =/0,b b=/0

(a ^ 3 * b ^ (- 4))/(a * b ^ (- 2))
ab^ 4 /a^ 3 b^ 2
- (a ^ 3 * b ^ 4)/(a * b ^ 2)
(a ^ 3 * b ^ 4)/(a * b ^ 2)

Step-by-step explanation:

Given the following Quadratic equation:

The steps to solve it are:

1. Substitute  into the equation:

2. Use the Quadratic formula .

In this case:

Substituting values into the Quadratic equation, you get (Round the values to the nearest hundreth):

3. The positive value is the time that the rocket will hit the ground.

Therefore, the rocket will hit the ground after .
