$$7² + 3^4-4^3 = ? – 11²$$​

Correct option is A

Given:

We are tasked to solve the equation:

​$$7^2 + 3^4 - 4^3 = ? - 11^2$$​

Solution:

Step 1: Simplify each term

1. Calculate $$7^2$$​ :

​$$7^2$$​ = 49

2. Calculate $$3^4$$​:

​$$3^4 = 3 \times 3 \times 3 \times 3 = 81$$​

3. Calculate $$4^3$$​ :

​$$4^3 = 4 \times 4 \times 4 = 64$$​

4. Calculate $$11^2$$​ :

​$$11^2$$​ = 121

Step 2: Simplify the left-hand side of the equation

​$$7^2 + 3^4 - 4^3 = 49 + 81 - 64$$​

49 + 81 = 130

130 - 64 = 66

Step 3: Substitute into the equation

The equation becomes:

66 = ? - 121

Step 4: Solve for ? :

? = 66 + 121

? = 187

Final Answer:

? = 187
