Welcome to our exponent calculator! We're exploring the concept of "138.4 to the power of 4". 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, 138.4 is the base, and 4 is the exponent.
Calculation
To calculate 138.4 to the power of 4, we multiply 138.4 by itself 4 times. Here's the step-by-step process:
| Step | Calculation | Result |
|---|---|---|
| 1 | 138.4 | 138.4 |
| 2 | 138.4 × 138.4 | 19154.56 |
| 3 | 138.4 × 138.4 × 138.4 | 2650991.104 |
| 4 | 138.4 × 138.4 × 138.4 × 138.4 | 366897168.7936 |
Solution: 138.4 to the power of 4 is equal to 366897168.7936.
