What is the value of 42x 4-2?a)16b)8c)1d)0Correct answer is option 'C'...
Answer:
The given expression is 42x4-2. We need to find the value of this expression.
To solve this expression, we need to follow the order of operations or the PEMDAS rule. PEMDAS stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
1. Multiplication:
The expression contains the multiplication operation, so we need to perform this operation first. We multiply 42 and 4, which gives us 168.
2. Subtraction:
After performing the multiplication operation, we have 168-2.
3. Subtraction:
Finally, we perform the subtraction operation, which gives us the value of the expression as 166.
Therefore, the correct answer is option 'C', which states that the value of 42x4-2 is 166.
In summary:
- The expression 42x4-2 is solved using the order of operations or PEMDAS rule.
- We perform the multiplication operation first, resulting in 168.
- Then, we subtract 2 from 168, giving us a final value of 166.
- Hence, option 'C' is the correct answer.
