Question
Evaluate: 11 + sqrt(-4 + 6 × 4 ÷ 3)
A. 11
B. 13
C. 15
D. 27
Answer: B. 13
Solution:
According to order of operations, inner brackets first where 6 × 4 ÷ 3 is first calculated since it has a multiplication and a division.
6 × 4 ÷ 3
= 24 ÷ 3
= 8
Hence,
11 + sqrt(-4 + 6 × 4 ÷ 3)
= 11 + sqrt(-4 + 8)
= 11 + sqrt(4)
= 11 + 2
= 13
Hence, The answer is 13.
