Match each number in scientific notation with the number written in standard form and in a step by step process.
geniusboy [140]

Answer:

1) Option 3

2) Option 1

3) Option 2

Step-by-step explanation:

To find : Match each number in scientific notation with the number written in standard form and in a step by step process.

Solution :

From scientific to standard we expand the power of 10.

1) 6.82\times 10^7

Remove decimal and open the power,

6.82\times 10^7=\frac{682}{100}\times 10000000

6.82\times 10^7=68200000

Therefore, 6.82\times 10^7=68,200,000

Match with Option 3.

2) 6.82\times 10^{-6}

Remove decimal and open the power,

6.82\times 10^{-6}=\frac{682}{100}\times \frac{1}{1000000}

6.82\times 10^{-6}=\frac{682}{100000000}

Therefore, 6.82\times 10^{-6}=0.00000682

Match with Option 1.

3) 6.82\times 10^6

Remove decimal and open the power,

6.82\times 10^6=\frac{682}{100}\times 1000000

6.82\times 10^6=6820000

Therefore, 6.82\times 10^6=6,820,000

Match with Option 2.
