Final answer:
By substituting the given values of a and b into the equation and performing the operations according to the order of operations, the answer calculated is 18. However, this does not match any of the provided options, suggesting an error in the question or options.
Step-by-step explanation:
To solve this problem, we need to substitute the values of a and b into the equation and then perform the operations according to the order of operations (PEMDAS/BODMAS). Here is the step-by-step calculation:
- First, substitute the given numbers: a=2 and b=4, into the equation. So the equation becomes: 2*4/2 + 48/2*2 + 4 - 2.
- According to the order of operations, multiplication and division operations are performed before addition and subtraction. Perform the operations from left to right. Our equation becomes: 4 + 48/4 + 4 - 2.
- This simplifies further to: 4 + 12 + 4 - 2.
- Add and subtract from left to right, we get: 16 + 4 - 2.
- Finally, we get our answer as 18.
However, none of the options provided in the question match with the calculated answer. Therefore, there might be a mistake in the question or the options given.
