`(85)^(2)` = ? +225

Answer

To solve the equation \( (85)^2 = ? + 225 \), we will follow these steps:

### Step 1: Calculate \( (85)^2 \)
First, we need to find the value of \( (85)^2 \).
\[ (85)^2 = 85 \times 85 \]
Calculating this gives:
\[ 85 \times 85 = 7225 \]

### Step 2: Set up the equation
Now, we can rewrite the equation using the value we just calculated:
\[ 7225 = ? + 225 \]

### Step 3: Isolate the question mark
To find the value of the question mark (let's denote it as \( x \)), we need to isolate \( x \) on one side of the equation:
\[ x + 225 = 7225 \]
Subtract 225 from both sides:
\[ x = 7225 - 225 \]

### Step 4: Perform the subtraction
Now, we will perform the subtraction:
\[ 7225 - 225 = 7000 \]

### Conclusion
Thus, the value of \( ? \) is:
\[ ? = 7000 \]

### Final Answer
The final answer is:
\[ (85)^2 = 7000 + 225 \]
