Question

How should the radical in the equation be isolated?

A) Subtract both sides by the exponent.
B) Raise each side to the same power as the index of the radical.
C) Square the equation.
D) Multiply both sides by the index.

Answer 1

To isolate the radical in the equation, raise each side to the same power as the index of the radical.

Step-by-step explanation:

To isolate the radical in the equation, we need to raise each side of the equation to the same power as the index of the radical. This means if we have a square root (index 2), we would square both sides of the equation.

Example:

If we have the equation √x = 4, we would square both sides to get x = 16.
