Correct Answer: C
Correct Answer: C
Method / Topic: Simplification
The answer follows the correct operation order or number rule.
Short Explanation
Detailed Explanation
Correct Answer: C
Method / Topic: Simplification
Apply the BODMAS rule: Brackets, Orders or powers/roots, Division and Multiplication from left to right, followed by Addition and Subtraction from left to right.
√64 = 8 and ∛27 = 3. Therefore 8 + 3 = 11.
CHECK:
Re-evaluating the expression in the correct BODMAS order gives 11, which matches option C.
EXAM TIP:
Do not perform addition or subtraction before completing brackets, powers, roots, multiplication and division. For fractions and decimals, simplify each product or quotient before combining terms.
A common error is to calculate strictly from left to right without respecting BODMAS, or to perform multiplication before an earlier division when both have equal priority.
PRACTICAL EXAMPLE:
Expressions involving bills, measurements or grouped calculations also require the same order of operations so that every person obtains the same numerical result.
Therefore, the correct
