Question

How do you convert 120,000,000,000,000 into scientific notation?

Answer 1

Scientific notation is `color(purple)(1.2 * 10^(14)`

Explanation:

`120,000,000,000,000`

`=> 120 * 10^(12)`

Scientific notation is `color(purple)(1.2 * 10^(14)`

Answer 2

`1.2*10^14`

Explanation:

The key realization is that when we write numbers in scientific notation, we want one digit before the decimal point.

In our case, we must loop it `14` times to the left. The number of times we loop it is our exponent, and looping left makes it positive. Thus, we have

`1.2*10^14`

Hope this helps!
