Square Roots and Cube Roots Flashcard Period 1

Front

What is a square root?

Back

A square root of a number is a value that, when multiplied by itself, gives the original number. For example, the square root of 9 is 3, because 3 x 3 = 9.

Front

What is a cube root?

Back

A cube root of a number is a value that, when multiplied by itself three times, gives the original number. For example, the cube root of 27 is 3, because 3 x 3 x 3 = 27.

Front

What is the formula to find the volume of a cube?

Back

The volume of a cube is calculated using the formula V = s³, where V is the volume and s is the length of one edge.

Front

If the volume of a cube is 64 cubic inches, what is the edge length?

Back

The edge length is 4 inches, because the cube root of 64 is 4 (4 x 4 x 4 = 64).

Front

How do you determine if an equation is true or false?

Back

To determine if an equation is true or false, evaluate both sides of the equation and see if they are equal.

Front

What is the relationship between square roots and perfect squares?

Back

A perfect square is a number that has an integer as its square root. For example, 16 is a perfect square because its square root is 4.

Front

What is the relationship between cube roots and perfect cubes?

Back

A perfect cube is a number that has an integer as its cube root. For example, 8 is a perfect cube because its cube root is 2.

Front

What is the square root of 25?

Back

The square root of 25 is 5, because 5 x 5 = 25.

Front

What is the cube root of 125?

Back

The cube root of 125 is 5, because 5 x 5 x 5 = 125.

Front

If v = 216 cubic inches, what is the edge length of a cube?

Back

The edge length is 6 inches, because the cube root of 216 is 6.
