398 to the Power of 2 = 398 2 = 158404
398 to the power of 2 = 158404
Welcome to our exponent calculator! We're exploring the concept of "398 to the power of 2". Let's break down what this means and how to calculate it.
What are Exponents?
An exponent is a mathematical operation where we multiply a number (called the base) by itself a certain number of times (indicated by the power or exponent). In our case, 398 is the base, and 2 is the exponent.
Calculation
To calculate 398 to the power of 2, we multiply 398 by itself 2 times. Here's the step-by-step process:
| Step | Calculation | Result |
|---|---|---|
| 1 | 398 | 398 |
| 2 | 398 × 398 | 158404 |
Solution: 398 to the power of 2 is equal to 158404.
How to write 398 to the power of 2 ?
Step 1: Understand the Concept
"398 to the power of 2" means we're multiplying 398 by itself 2 times. Let's break this down:
Step 2: Learn the Notation
In mathematics, we have a special way to write this more concisely. We use superscript notation:
Here, 398 is called the "base", and 2 is called the "exponent" or "power".
Step 3: Understand Alternative Notations
Sometimes, especially when typing or in programming, you might see it written as:
This means the same thing as 3982.
Step 4: Calculate the Result

Exponent Properties
1. Multiplying exponents with the same base: 398a * 398b = 398(a+b)
Example: 3982 * 3983 = 3985 = 9986547231968
2. Dividing exponents with the same base: 398a / 398b = 398(a-b)
Example: 3985 / 3982 = 3983 = 63044792
