Question

match the given equation with the correct first step for solving it.$sqrt{x+3}=7$choose the correct answer below.a. raise each side of the equation to the power $\frac{2}{3}$.b. square each side of the equation.c. let $u=(x+3)^{\frac{1}{3}}$ and $u^{2}=(x+3)^{\frac{2}{3}}$.d. multiply each side of the equation by $x(x+3)$.e. cube each side of the equation.

Explanation:

Step1: Identify radical type

The equation has a square root ($\sqrt{x+3}$ is equivalent to $(x+3)^\frac{1}{2}$).

Step2: Determine inverse operation

To eliminate a square root, the inverse operation is squaring both sides.

Answer:

B. Square each side of the equation.
