Correct Answer :
36
Solution :
The correct option is 36.
To find the value of the given mathematical expression, we will simplify each term step-by-step following the standard order of operations (PEMDAS/BODMAS).
The given expression is:
Step 1: Simplify terms inside parentheses
We first calculate the division inside the parentheses:
Substituting this back, the expression becomes:
Step 2: Evaluate the exponents (powers)
Now we calculate the value of each exponential term:
1. First term: 43 = 4 × 4 × 4 = 64
2. Second term: 72 = 7 × 7 = 49
3. Third term: 42 = 4 × 4 = 16
Substituting these values back into the expression, we get:
Step 3: Perform multiplication
Next, evaluate the multiplication at the end of the expression:
9 × 1 = 9
So, the expression becomes:
Step 4: Perform addition and subtraction from left to right
Let us perform the calculations sequentially from left to right:
1. 64 - 49 = 15
The expression now is: 15 + 16 - 4 + 9
2. 15 + 16 = 31
The expression now is: 31 - 4 + 9
3. 31 - 4 = 27
The expression now is: 27 + 9
4. 27 + 9 = 36
Thus, the final value of the expression is 36.
