Question

How do you write 4, 300, 000 in scientific notation?

Answer 1

`4300000` in scientific notation is `4.3xx10^6`

Explanation:

In scientific notation a number is written as `axx10^n`, where `n` is an integer and `a` is a number which has just one digit to the left of decimal i.e. `1<=a<10`.

Hence to write `4300000` in scientific notation, we will have to move decimal six places to the left.

Hence `4300000` in scientific notation is `4.3xx10^6`

Answer 2

`4.3*10^6`

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 `6` times to the left. The number of times we loop it is the exponent, and looping right makes it positive. Thus, we have

`4.3*10^6`

Hope this helps!
