What is 30,000 written in scientific notation?

Answer 1

The scientific notation of 30,000 is
The goal of writing a number in scientific notation is to have a decimal number, with one digit to theleft of the decmial point, followed by a × 10 to some power.
To format your number in this way, we'll divide the 30000 by 10, 4 time(s), making it a 3.
do this, because each division by 10 moves the decimal point to the left one digit.
But in order to keep our number the same number, we must have a × 104 next to the 3.


So, the final answer is 3 × (10 to the 4th power)
