Question

Solve the equation. If necessary, round your answer to the nearest tenth. x2 = 324

Answer 1

Dividing 2 on both sides of the equal sign will give you x=162 ; rounding it is 160.

Answer 2

X × w = 324

First, regroup terms. / Your problem should look like: 2x = 324.
Second, divide both sides by 2. / Your problem should look like: x = $\frac{324}{2}$ .
Third, simplify $\frac{324}{2}$ to 162. / Your problem should look like: x = 162.

Original answer: x = 162.
Rounded to the nearest tenth: x = 160.
