Simplifying the Expression (2x)^-4/x^-1*x
This article will guide you through simplifying the expression (2x)^-4/x^-1*x. We'll break down the steps using the rules of exponents.
Understanding the Rules of Exponents
Before we begin, let's review some key exponent rules:
- Product of Powers: x^m * x^n = x^(m+n)
- Quotient of Powers: x^m / x^n = x^(m-n)
- Power of a Power: (x^m)^n = x^(m*n)
- Negative Exponent: x^-n = 1/x^n
Simplifying the Expression
-
Simplify the numerator:
- (2x)^-4 = 1/(2x)^4 (using the negative exponent rule)
- 1/(2x)^4 = 1/(2^4 * x^4) = 1/(16x^4) (using the power of a power rule)
-
Simplify the denominator:
- x^-1 = 1/x (using the negative exponent rule)
-
Rewrite the expression:
- The original expression becomes: (1/(16x^4)) / (1/x) * x
-
Dividing by a fraction is the same as multiplying by its inverse:
- (1/(16x^4)) * (x/1) * x
-
Simplify:
- (x * x) / (16x^4) = x^2 / 16x^4
-
Apply the Quotient of Powers Rule:
- x^2 / 16x^4 = 1 / (16x^(4-2)) = 1 / (16x^2)
Final Result
Therefore, the simplified form of the expression (2x)^-4/x^-1*x is 1 / (16x^2).
