What is the equivalent of the square root of X in terms of exponents?

• X to the power of 3

• X to the power of 1/2

• X to the power of 2

• X to the power of 1/3

In the equation 'square root of (X plus nine) equals five', what should be done first to solve for X?

• Subtract nine from both sides

• Square both sides

• Add nine to both sides

• Take the cube root of both sides

What is the first step in solving an equation with a square root?

• Take the cube root of both sides

• Square both sides

• Add a constant to both sides

• Subtract a constant from both sides

What operation is the opposite of taking a square root?

• Squaring

What is the result of squaring a square root?

• It squares the value

• It halves the value

• It doubles the value

• It eliminates the square root

What is the result of raising a number to the power of 1/2 and then squaring it?

• The original number

• Half the original number

• Twice the original number

• The square of the original number

How can the equation 'X plus two to the three halves power equals eight' be simplified?

• Raise both sides to the power of 3/2

• Raise both sides to the power of 2/3

• Take the square root of both sides

• Square both sides
