Example 1 – Solve: 3x3 = 12x
Step 1: Write the equation in the correct form. In this case, we need to set the equation equal to zero with the terms written in descending order.
 3x^3-12=0
Step 2: Use a factoring strategies to factor the problem.
 3x(x^2-4)=0
3x(x+2)(x-2)=0
Step 3: Use the Zero Product Property and set each factor containing a variable equal to zero.
 3x=0 or x+2=0 or x-2=0
Step 4: Solve each factor that was set equal to zero by getting the x on one side and the answer on the other side.
 x=0 or x=-2 or x=

Answer:
115ft^2
Step-by-step explanation:
10 * 11.5 = 115

Before answering the exact question you sent, you have to understand one simple principle: there are two forms of a variable with a fraction as an exponent, exponential form and radical form.
Example:
![exponential\ form = x^{1/3}\\radical form = \sqrt[3]{x}](https://tex.z-dn.net/?f=exponential%5C%20form%20%3D%20x%5E%7B1%2F3%7D%5C%5Cradical%20form%20%3D%20%20%5Csqrt%5B3%5D%7Bx%7D%20)
If the exponent is a fraction, the denominator of the fraction is the number on the outside of the radical sign.
So, for #23, you would change
![\sqrt[3]{a}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7Ba%7D%20)
to

. Then, because the a is the same after the 2 and the 3, you can add them up to get

.
For #24, you'd do almost the same thing (change the radical-b's to

and

. However, you can't add them up because the exponents are different (1/4 and 1/3), so you'd leave it as
