Answer :

Sure! Let's match each expression on the left with its equivalent number on the right.

1. Expression: [tex]\(8,200 \times 10\)[/tex]

To solve this, multiply 8,200 by 10. Multiplying by 10 means shifting all digits to the left by one place, which gives us 82,000.

So, [tex]\(8,200 \times 10 = 82,000\)[/tex].

2. Expression: [tex]\(820,000 \div 10,000\)[/tex]

To solve this, divide 820,000 by 10,000. Dividing by 10,000 means reducing the number of zeros or shifting the decimal point four places to the left. This results in 82.

So, [tex]\(820,000 \div 10,000 = 82\)[/tex].

3. Expression: [tex]\(820 \times 10,000\)[/tex]

To solve this, multiply 820 by 10,000. Multiplying by 10,000 means adding four zeros or shifting all digits to the left by four places, which gives us 8,200,000.

So, [tex]\(820 \times 10,000 = 8,200,000\)[/tex].

4. Expression: [tex]\(8,200 \div 10\)[/tex]

To solve this, divide 8,200 by 10. Dividing by 10 means reducing the number of zeros or shifting the decimal point one place to the left, resulting in 820.

So, [tex]\(8,200 \div 10 = 820\)[/tex].

Now let's match each expression with the equivalent value:

- [tex]\(8,200 \times 10\)[/tex] is equivalent to 82,000.
- [tex]\(820,000 \div 10,000\)[/tex] is equivalent to 82.
- [tex]\(820 \times 10,000\)[/tex] is equivalent to 8,200,000.
- [tex]\(8,200 \div 10\)[/tex] is equivalent to 820.
