Whether you are asking: “what is 18 to the power of 100?” or “what is 18 to the 100 power?” or “what is 18 raised to the power of 100?” or “what is 18 raised to 100?” you are looking to perform a mathematical operation called exponentiation of 18 to the power of 100. Don’t be confused by the term “exponentiation”. The calculation itself is not too complex. But before we explain the details of the calculation, here is your answer:
18 to the power of 100 = 18100 = 18^100 = 3.3670573242752E+125
ANSWER: 3.3670573242752E+125

Raising 18 to the Power of 100 Explained
First, let’s clarify the terms. We mentioned that we are performing exponentiation when we raise 18 to the power of 100. While performing exponentiation we multiply a number called base (mathematically denoted as “b” or “x”) by itself a certain number of times (mathematically denoted as “n” or “y”). The “number of times” is called exponent. To sum up, in this example 18 is the base (b) and 100 is an exponent (n).
Mathematical Expression for 18 to the 100 Power
There are two ways how raising 18 to the 100 power is written. You can write this expression with a superscript which is a small number written immediately above and to the right of the base as shown below:
18100
Another way to write 18 to the 100 power is to use the caret (^) symbol. For example, this comes handy for calculations in Excel where you perform exponentiation using caret (^) symbol. Here is the expression:
18^100
Does not matter whether you use a superscript or a caret symbol to write the expression the underpinning formula looks like this:
18 to the power of 100 = 18 x … x 18 (100 times)
To recap 18 is the base and 100 is the exponent (number of times that you multiply the base with).
How to solve 18 to the 100 power on a scientific calculator
If you are using a scientific calculator you can quickly raise 18 to the power of 100 following these steps:
- Type 18 in the calculator
- Then press “xy” button
- Enter 100 and hit “=”
You will notice that the calculator expression uses the caret (^) symbol as opposed to a superscript.
