Whether you are asking: “what is 18 to the power of 81?” or “what is 18 to the 81 power?” or “what is 18 raised to the power of 81?” or “what is 18 raised to 81?” you are looking to perform a mathematical operation called exponentiation of 18 to the power of 81. 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 81 = 1881 = 18^81 = 4.7541503630913E+101
ANSWER: 4.7541503630913E+101

Raising 18 to the Power of 81 Explained
First, let’s clarify the terms. We mentioned that we are performing exponentiation when we raise 18 to the power of 81. 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 81 is an exponent (n).
Mathematical Expression for 18 to the 81 Power
There are two ways how raising 18 to the 81 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:
1881
Another way to write 18 to the 81 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:
18^81
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 81 = 18 x … x 18 (81 times)
To recap 18 is the base and 81 is the exponent (number of times that you multiply the base with).
How to solve 18 to the 81 power on a scientific calculator
If you are using a scientific calculator you can quickly raise 18 to the power of 81 following these steps:
- Type 18 in the calculator
- Then press “xy” button
- Enter 81 and hit “=”
You will notice that the calculator expression uses the caret (^) symbol as opposed to a superscript.
