Whether you are asking: “what is 15 to the power of 86?” or “what is 15 to the 86 power?” or “what is 15 raised to the power of 86?” or “what is 15 raised to 86?” you are looking to perform a mathematical operation called exponentiation of 15 to the power of 86. 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:

15 to the power of 86 = 1586 = 15^86 = 1.3926701872283E+101

Raising 15 to the Power of 86 Explained

First, let’s clarify the terms. We mentioned that we are performing exponentiation when we raise 15 to the power of 86. 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 15 is the base (b) and 86 is an exponent (n).

Mathematical Expression for 15 to the 86 Power

There are two ways how raising 15 to the 86 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:

1586

Another way to write 15 to the 86 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:

15^86

Does not matter whether you use a superscript or a caret symbol to write the expression the underpinning formula looks like this:

15 to the power of 86 = 15 x … x 15 (86 times)

To recap 15 is the base and 86 is the exponent (number of times that you multiply the base with).

How to solve 15 to the 86 power on a scientific calculator

If you are using a scientific calculator you can quickly raise 15 to the power of 86 following these steps:

  • Type 15 in the calculator
  • Then press “xy” button
  • Enter 86 and hit “=”

You will notice that the calculator expression uses the caret (^) symbol as opposed to a superscript.
