Answer :

Certainly! Let's go through the multiplication step-by-step.

We need to multiply [tex]\( 57 \)[/tex] by [tex]\( 70 \)[/tex].

1. First, break down the numbers to simplify:
[tex]\[ 57 \times 70 = 57 \times (7 \times 10) \][/tex]

2. Using the associative property of multiplication, group the numbers:
[tex]\[ 57 \times (7 \times 10) = (57 \times 7) \times 10 \][/tex]

3. Calculate [tex]\( 57 \times 7 \)[/tex]:
- Multiply [tex]\( 57 \)[/tex] by [tex]\( 7 \)[/tex]:
[tex]\[ 57 \times 7 = 399 \][/tex]

4. Now, multiply the result by [tex]\( 10 \)[/tex]:
[tex]\[ 399 \times 10 = 3990 \][/tex]

Therefore,
[tex]\[ 57 \times 70 = 3990 \][/tex]

So, the final answer is:
[tex]\[ 57 \times 70 = 3990 \][/tex]
