Question

Describe how you could use inverse operations to solve the equation sqrt(x) = 4.

A) Subtract 4 from both sides of the equation to isolate sqrt(x), then square both sides to find the value of x.
B) Add 4 to both sides of the equation to isolate sqrt(x), then square both sides to find the value of x.
C) Multiply both sides of the equation by 4 to isolate x, then take the square root to find the value of sqrt(x).
D) Divide both sides of the equation by 4 to isolate x, then take the square root to find the value of sqrt(x).

Answer 1

To solve the equation sqrt(x) = 4 using inverse operations, add 4 to both sides of the equation to isolate sqrt(x) and then square both sides to find the value of x.

Step-by-step explanation:

To solve the equation sqrt(x) = 4 using inverse operations, we can follow these steps:

1. Option B: Add 4 to both sides of the equation to isolate sqrt(x).
2. Square both sides of the equation to find the value of x. This can be done by squaring the square root of x and squaring 4.

The correct option is B) Add 4 to both sides of the equation to isolate sqrt(x), then square both sides to find the value of x.
