Question

Sure, let’s solve the expression step by step:

Simplify inside the parentheses: ( 70 - 6 = 64 )
Multiply: ( 4 \times 64 = 256 )
Multiply: ( 15 \times 805 = 12075 )
Add the results: ( 12075 + 256 = 12331 )
So, the expression ( 15 \cdot 805 + 4(70 - 6) ) simplifies to 12331.

Answer 1

Let’s go through the expression step by step as you've outlined:

1. Simplify inside the parentheses:
\[
70 - 6 = 64
\]

2. Now, multiply:
\[
4 \times 64 = 256
\]

3. Next, multiply the other part of the expression:
\[
15 \times 805 = 12075
\]

4. Finally, add the results of the two multiplications together:
\[
12075 + 256 = 12331
\]

So, the final result of the expression \( 15 \cdot 805 + 4(70 - 6) \) simplifies to \( \boxed{12331} \). Your calculations are correct!
