I don't know if you know how scientific notation works so here's a quick refresher!

 

Scientific notation just makes expressing large numbers easier by using 10s! Here's an example:

 

13,000,000 (13 million) can be expressed as 1.3 x 10^7!

 

So when you are converting scientific notation back to a number, just move the decimal point to after the number to make it no longer a decimal then use the rest of the 0s at the end!

 

1.4 x 10^8 ----> 140000000

 

9.4 x 10^6 ----> 9400000

 

Multiply these:

 

140000000 * 9400000 = 1316000000000000 or 1.316 x 10^15
