Expression Simplifying Calculator Negative Exponents
This calculator helps simplify mathematical expressions containing negative exponents. Learn how to handle negative exponents in your calculations with our step-by-step guide and examples.
How to Use This Calculator
Enter your mathematical expression in the input field below. The calculator will simplify the expression by converting negative exponents to positive exponents and applying exponent rules.
For example, if you enter x^-3, the calculator will simplify it to 1/(x^3).
Note: This calculator handles basic exponent rules. For more complex expressions, you may need to simplify manually.
Rules for Negative Exponents
Negative exponents follow specific rules that help simplify expressions:
- Negative Exponent Rule: For any non-zero number a and integer n,
a^-n = 1/(a^n). - Combining Exponents: When multiplying terms with the same base, add the exponents:
a^m * a^n = a^(m+n). - Power of a Power: When raising a power to another power, multiply the exponents:
(a^m)^n = a^(m*n).
Example: x^-2 * x^3 = x^(-2+3) = x^1 = x
Worked Examples
Example 1: Simple Negative Exponent
Expression: 5^-2
Simplified: 1/(5^2) = 1/25
Example 2: Combining Exponents
Expression: 2^-3 * 2^4
Simplified: 2^(-3+4) = 2^1 = 2
Example 3: Power of a Power
Expression: (3^-2)^3
Simplified: 3^(-2*3) = 3^-6 = 1/(3^6)
Frequently Asked Questions
What is a negative exponent?
A negative exponent indicates the reciprocal of the base raised to the positive exponent. For example, a^-n = 1/(a^n).
How do I simplify an expression with negative exponents?
Convert the negative exponent to a positive exponent in the denominator. For example, x^-3 becomes 1/(x^3).
Can I use this calculator for variables with negative exponents?
Yes, the calculator handles variables with negative exponents. Just enter the expression with the negative exponent, and the calculator will simplify it.
