Negative exponent calculator
The exponent calculator will calculate the value of any base raised to any power. This page will cover all the related topics, including the negative exponent. Let's start with the basics. An exponent is a way to represent how many times a number, known as the base, is multiplied by itself.

Plus, the calculated results will include either an exponential multiplication chart for positive exponents or a decimal conversion chart for negative exponents. A Data Record is a set of calculator entries that are stored in your web browser's Local Storage. If a Data Record is currently selected in the "Data" tab, this line will list the name you gave to that data record. If no data record is selected, or you have no entries stored for this calculator, the line will display "None". Enter the base number integers only of the exponential expression.

Negative Exponents: 8 Things Your Students Need To Know
Exponentiation is a mathematical operation, written as a n , involving the base a and an exponent n. In the case where n is a positive integer, exponentiation corresponds to repeated multiplication of the base, n times. The calculator above accepts negative bases, but does not compute imaginary numbers. It also does not accept fractions, but can be used to compute fractional exponents, as long as the exponents are input in their decimal form. When an exponent is negative, the negative sign is removed by reciprocating the base and raising it to the positive exponent. Similarly, when divided bases are raised to an exponent, the exponent is distributed to both bases. When an exponent is 0, the result of the exponentiation of any base will always be 1, although some debate surrounds 0 0 being 1 or undefined. For many applications, defining 0 0 as 1 is convenient.
This is an online calculator for exponents.
In science, we deal with numbers that are sometimes extremely large or extremely small. It helps to have a calculator around when doing math with such large numbers but you have to know how to use one. There are ,,,,,,, molecules in 18 grams of water.
How to Use Exponents on a Scientific Calculator
Scientific calculators have more functionality that business calculators, and one thing they can do that is especially useful for scientists is to calculate exponents. On most calculators, you access this function by typing the base, the exponent key and finally the exponent. Although this is the convention, it's always good to do a test, because some calculators may require you to enter the numbers in reverse order. Scientific calculators are easy to distinguish from business calculators because of their many extra function keys. If you aren't sure if you have a scientific calculator, try this calculation:. A scientific calculator will automatically do the multiplication first and give 13 as the answer. A business calculator will do the operations in the order you enter them and give Here are just a few of the functions on a scientific calculator that you won't find on a business calculator:. In addition to these keys, scientific calculators usually have two keys for exponential functions:. Suppose you want the value y x. On most calculators, you enter the base, press the exponent key and enter the exponent. Here's an example:.
How Can An Exponent Be Negative?
You already know that an exponent represents the number of times you have to multiply a number by itself. But what if your variable is being raised to a negative exponent? A negative exponent is equivalent to the inverse of the same number with a positive exponent. In other words:. There is nothing special about solving a problem that includes negative exponentials.
