Which operation is NOT explicitly part of the PEMDAS rule?

• A. Exponents
• B. Parentheses
• C. Square roots
• D. Multiplication

Answer: (C)

The correct answer, square roots, is not explicitly included in the PEMDAS rule. PEMDAS is an acronym that stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). While square roots are a mathematical operation that falls under the broader category of exponents (since a square root can be expressed as an exponent of 1/2), the PEMDAS rule specifically mentions exponents but does not list square roots as a separate operation. This means that when following the order of operations, the focus is on handling parentheses first, then any exponentiation, followed by multiplication and division, and finally addition and subtraction. In contrast, parentheses, exponents, and multiplication are all specifically named in the PEMDAS rule, hence making clear their roles in the order of operations.
