Simplifying Expressions with Exponents
This article will explore the simplification of the expression (x^4)^2 = x^12 / x^5 where x is not equal to 0.
Understanding the Properties of Exponents
The problem involves two key properties of exponents:
- Power of a power: (x^m)^n = x^(m*n)
- Division of powers with the same base: x^m / x^n = x^(m-n)
Simplifying the Expression
Let's break down the simplification step-by-step:
- Simplify the left side: (x^4)^2 = x^(4*2) = x^8
- Simplify the right side: x^12 / x^5 = x^(12-5) = x^7
Now we have: x^8 = x^7.
Note: For this equation to be true, x must be equal to 1. This is because any number raised to the power of 8 will be greater than the same number raised to the power of 7 unless that number is 1.
Conclusion
The expression (x^4)^2 = x^12 / x^5 simplifies to x^8 = x^7. This equation holds true only when x = 1. The key to solving this type of problem is understanding and applying the basic properties of exponents.
