Operations with Rational Exponents
Operations with Rational Exponents is a skill on Pengi from Lesson 3: Rational Exponents in Yoshiwara Intermediate Algebra.
Key Concepts
Property Powers with rational exponents obey the same laws of exponents as powers with integer exponents. For a base $a 0$ and rational exponents $p$ and $q$:.
1. First Law (Product of Powers): $a^p \cdot a^q = a^{p+q}$ 2. Second Law (Quotient of Powers): $\frac{a^p}{a^q} = a^{p q}$ 3. Third Law (Power of a Power): $(a^p)^q = a^{pq}$ 4. Fourth Law (Power of a Product): $(ab)^p = a^p b^p$.
Examples To simplify $x^{1/2} \cdot x^{1/4}$, we add the exponents: $x^{1/2 + 1/4} = x^{2/4 + 1/4} = x^{3/4}$.
