Answer 1

To evaluate the expression \((4 \times 5)^2 - 6 + 3\), we can proceed with the following steps:

1. **Calculate \(4 \times 5\)**:
\[
4 \times 5 = 20
\]

2. **Next, evaluate \((4 \times 5)^2\)**:
\[
(20)^2 = 400
\]

3. **Now substitute this back into the expression**:
\[
400 - 6 + 3
\]

4. **Perform the subtraction and addition**:
\[
400 - 6 = 394
\]
\[
394 + 3 = 397
\]

Therefore, the final result is:
\[
\boxed{397}
\]
