    Answer:

    C) To square a number, multiply the number by itself.

    Step-by-step explanation:

    A) is incorrect because square roots are made by multiplying the number to itself.

    2 × 2  is the same as 2²

    3 × 3 is the same as 3²

    4 × 4 is the same as 4²

    2² = 4

    3² = 9

    4² = 16

    B) is incorrect because the inverse of squaring is finding the square root.

    2² inverse is √4

    3² inverse is √9

    4² inverse is √16

    D) is incorrect because perfect squares can be odd or even

    A perfect square is a number made by squaring a whole number.

    4, 9, 16, 25, 36, 49, 64, 81, 100, 121, and 144 are all examples of perfect squares.
