6 + 5 × 22 + 1

A
121


B
107


C
27


D
16

Answer 1

[C] 27

Explanation:

Based on PEMDAS:

• Parentheses
• Exponents
• Multiplication
• Division
• Addition
• Subtraction

Therefore,

6 + 5 × 2² + 1

There are no Parentheses and but there are exponents so

2² is 4 ; [ 2 × 2 = 4]

Now we have;

6 + 5 × 4 + 1

Next, we have Multiplication next so; [ 5 × 4 = 20]

6 + 20 + 1

Finally, we add them up;

6 + 20 + 1

26 + 1

= 27

Hence, the answer is [C] 27.
