− 6 + 3 =

Answer 1

Let's evaluate the expression step-by-step:

Given:
\[
(4 \times 5)^2 - 6 + 3
\]

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

2. **Now substitute back into the expression**:
\[
(20)^2 - 6 + 3
\]

3. **Calculate \((20)^2\)**:
\[
20^2 = 400
\]

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

5. **Next, calculate \(400 - 6\)**:
\[
400 - 6 = 394
\]

6. **Finally, add \(3\)**:
\[
394 + 3 = 397
\]

Thus, the evaluated result of the expression is:
\[
\boxed{397}
\]
