Simplifying Exponential Expressions: (x^4)^-3 x 2x^4
This article will guide you through simplifying the expression (x^4)^-3 x 2x^4. We will use the rules of exponents to break down the expression and arrive at a simplified form.
Understanding the Rules of Exponents
Before we dive into simplification, let's review the relevant rules of exponents:
- Power of a power: (x^m)^n = x^(m*n)
- Product of powers: x^m * x^n = x^(m+n)
Simplifying the Expression
-
Simplify (x^4)^-3: Using the "power of a power" rule, we get: (x^4)^-3 = x^(4*-3) = x^-12
-
Simplify 2x^4: This term is already in its simplest form.
-
Combine the simplified terms: Now we have: x^-12 * 2x^4
-
Apply the "product of powers" rule: x^-12 * 2x^4 = 2x^(-12+4) = 2x^-8
-
Express with a positive exponent: Since x^-8 is equivalent to 1/x^8, the final simplified expression is: 2/x^8
Conclusion
By applying the rules of exponents, we successfully simplified the expression (x^4)^-3 x 2x^4 to 2/x^8. Remember, understanding the rules of exponents is crucial for working with expressions that involve powers.
