What is the term for the number that when multiplied by itself equals the original number?

• A. Square
• B. Square root
• C. Cube root
• D. Base

Answer: (B)

The term for the number that, when multiplied by itself, equals the original number is known as the square root. In mathematical terms, if you have a number \( x \), the square root of \( x \) is a number \( y \) such that \( y \times y = x \). For example, the square root of 16 is 4, since \( 4 \times 4 = 16 \). Understanding square roots is essential in various arithmetic reasoning problems, particularly those involving areas, geometric computations, or solving quadratic equations. The other terms specified—such as square, cube root, and base—do not correctly define the relationship described in the question. The square is the result of multiplying a number by itself, rather than the number itself. A cube root refers to a number that, when multiplied by itself three times, equals the original number, and base usually pertains to the foundational number in exponential expressions. Therefore, square root is the precise term that fits the description given in the question.
