Whether you are asking: “what is 15.9 to the power of 2?” or “what is 15.9 to the 2 power?” or “what is 15.9 raised to the power of 2?” or “what is 15.9 raised to 2?” you are looking to perform a mathematical operation called exponentiation of 15.9 to the power of 2. 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:
15.9 to the power of 2 = 15.92 = 15.9^2 = 252.81
ANSWER: 252.81

Raising 15.9 to the Power of 2 Explained
First, let’s clarify the terms. We mentioned that we are performing exponentiation when we raise 15.9 to the power of 2. 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 15.9 is the base (b) and 2 is an exponent (n).
Mathematical Expression for 15.9 to the 2 Power
There are two ways how raising 15.9 to the 2 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:
15.92
Another way to write 15.9 to the 2 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:
15.9^2
Does not matter whether you use a superscript or a caret symbol to write the expression the underpinning formula looks like this:
15.9 to the power of 2 = 15.9 x … x 15.9 (2 times)
To recap 15.9 is the base and 2 is the exponent (number of times that you multiply the base with).
How to solve 15.9 to the 2 power on a scientific calculator
If you are using a scientific calculator you can quickly raise 15.9 to the power of 2 following these steps:
- Type 15.9 in the calculator
- Then press “xy” button
- Enter 2 and hit “=”
You will notice that the calculator expression uses the caret (^) symbol as opposed to a superscript.
