Answer:

Option 3 - \(8.24\times 10^6=8,240,000\)

Step-by-step explanation:

Given : Number - \(8.24\times 10^6\)

To find : Re-write the number into standard notation?

Solution :                  

Standard notation in the expansion of scientific notation.

Scientific notation \(8.24\times 10^6\)

\(10^6\) means 10 with 6 zeros i.e. 1000000

So,  \(=8.24\times 1000000\)

Removing decimal,

\(=\frac{824}{100}\times 1000000\)

\(=824\times 10000\)

\(=8240000\)

Therefore,  \(8.24\times 10^6=8,240,000\)

So, Option 3 is correct.
