Simplifying (5x^3)(-3x^-2)
This expression involves multiplying two terms with exponents. Let's break down the simplification process step-by-step.
Understanding the Properties of Exponents
- Multiplication of powers with the same base: When multiplying powers with the same base, we add the exponents.
- Example: x^m * x^n = x^(m+n)
- Negative exponents: A term with a negative exponent in the numerator can be rewritten with a positive exponent in the denominator, and vice versa.
- Example: x^-n = 1/x^n
Simplifying the Expression
- Multiply the coefficients: (5)(-3) = -15
- Apply the rule for multiplying powers with the same base: x^3 * x^-2 = x^(3+(-2)) = x^1
- Simplify x^1: x^1 = x
Final Result
Therefore, the simplified form of (5x^3)(-3x^-2) is -15x.
