### What means E10?

E10 means move the decimal to the right 10 places. If the number 1-9 is a whole number, then the decimal may not be seen, but for the purposes of moving the decimal, there is an invisible decimal after each whole number.

**How do you write to the power of 10 in JavaScript?**

To get the exponent power of a number, use the Math. pow (base, exponent ) method. This method returns the base to the exponent power, that is, base exponent. base − The base number.

## What is the E in scientific notation?

In statistics, the symbol e is a mathematical constant approximately equal to 2.71828183. Prism switches to scientific notation when the values are very large or very small. For example: 2.3e-5, means 2.3 times ten to the minus five power, or 0.000023.

## How do you write e notation?
