How do I write it in exponential notation? And what is the formula

A number can be written as a product or multiple of two numbers out of which one is the the power of 10 and the other a decimal number. This form is said to be the exponential notation. An exponential notation allows you to move the decimal place of a number by increasing or decreasing the power of 10. Hence the exponential notation of 3125 would be:

3.125*10

The power 3 is there as we have moved the decimal place three points to the right.

3.125*10

^{3}The power 3 is there as we have moved the decimal place three points to the right.

You got me there. I'm over 50 and never seen or needed one. Just leave it.

Lol.
