Question #e4ea3

Answer 1

`6.8*10^6`

Imagine the decimal point at the end of the number like this: `6,800,000.`

Now move it over until it comes right in between the first two numbers. The number of times the decimal point moves is the exponent on the 10.

Answer 2

`6.8*10^6`

Explanation:

When writing numbers in scientific notation, we want to have one non-zero digit in front of the decimal point. In this example, we can loop the decimal 6 times to the left, so that we get:

6.800000

We looped the decimal 6 times. This will be the power of 10 that we use.

`6.8*10^6`
