# How to write an exponential notation with positive exponents rule

To write a number in scientific notation, move the decimal point to the right of the first digit in the number. Warning: A negative on an exponent and a negative on a number mean two very different things! The exponential term only places the decimal point.

Example: 2. Introduction to Exponents - Rules of Exponents Since we often see exponents throughout all math courses, it is important to understand the rules of exponents. Looks like we moved it to the right. The exponent applies only to the number that it is next to. The exponent is negative because we moved the decimal point to the right. The end result is changed so that there is only one nonzero digit to the left of the decimal. Then the power on 10 will be a negative 9, and the answer is 5.

Perform the same series of steps as above, except move the decimal point to the right. The quotient is changed if necessary so that there is only one nonzero digit to the left of the decimal. Introduction to Exponents - Rules of Exponents Since we often see exponents throughout all math courses, it is important to understand the rules of exponents. In scientific notation, the number part as opposed to the ten-to-a-power part will be "4.

## Laws of exponents

Since I'd moved it two places, then I'd be dealing with a power of 2 on Example: Oops - the answer really is 4. Other extreme numbers include the width of a human hair, which is about 0. This is what we should expect for a small number. For example, growth occurs in living organisms by the division of cells. To convert this to scientific notation, I first convert the "" to "1. You substitute the value of the variable into the expression and simplify. To get from where it is to right after the 9, the decimal point will need to move seven places to the left. The exponential term only places the decimal point. The zeros are only place holders. So, our count is - 4.

It's important to understand the rules of multiplying exponents so that we can simplify expressions with exponents. The conversion is fairly simple.
