Read the instructions below.
`A**B=A^(3)-B^(3)`
`A+B=A-B`
`A-B=A//B` and
find the value of `(3**4) -(8+12)`.

Options

A. 9
B. `9.25`
C. `-9.25`
D. None of these

Answer

To solve the expression `(3**4) - (8 + 12)` using the given operations, we will follow the defined instructions step by step.

### Step 1: Calculate `3**4`
According to the instruction, `A**B = A^3 - B^3`. Here, we have:
- A = 3
- B = 4

Now we calculate:
\[ 3**4 = 3^3 - 4^3 \]
Calculating the cubes:
\[ 3^3 = 27 \]
\[ 4^3 = 64 \]
Now substitute these values:
\[ 3**4 = 27 - 64 \]
Calculating the difference:
\[ 3**4 = -37 \]

### Step 2: Calculate `8 + 12`
According to the instruction, `A + B = A - B`. Here, we have:
- A = 8
- B = 12

Now we calculate:
\[ 8 + 12 = 8 - 12 \]
Calculating the difference:
\[ 8 + 12 = -4 \]

### Step 3: Combine the results
Now we need to find the value of `(3**4) - (8 + 12)`. We have:
\[ (3**4) - (8 + 12) = -37 - (-4) \]
This simplifies to:
\[ -37 + 4 = -33 \]

### Final Result
Thus, the value of `(3**4) - (8 + 12)` is:
\[ -33 \]
