140 to the Power of 2 = 140 2 = 19600
140 to the power of 2 = 19600
Welcome to our exponent calculator! We're exploring the concept of "140 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, 140 is the base, and 2 is the exponent.
Calculation
To calculate 140 to the power of 2, we multiply 140 by itself 2 times. Here's the step-by-step process:
| Step | Calculation | Result |
|---|---|---|
| 1 | 140 | 140 |
| 2 | 140 × 140 | 19600 |
Solution: 140 to the power of 2 is equal to 19600.
How to write 140 to the power of 2 ?
Step 1: Understand the Concept
"140 to the power of 2" means we're multiplying 140 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, 140 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 1402.
Step 4: Calculate the Result

Exponent Properties
1. Multiplying exponents with the same base: 140a * 140b = 140(a+b)
Example: 1402 * 1403 = 1405 = 53782400000
2. Dividing exponents with the same base: 140a / 140b = 140(a-b)
Example: 1405 / 1402 = 1403 = 2744000
