Teacher presentation materials. Unit: Alg2.3 Complex Numbers and Rational Exponents (Algebra 2). Alg2.3 Complex Numbers and Rational Exponents In this unit, students use what they know about exponents and radicals to extend exponent rules to include rational exponents (for example, \(5^{\frac{1}{3}}=\sqrt[3]{5}\) ), solve various equations involving squares and square roots, develop the concept of complex numbers by defining a new number \(i\) whose square is -1, and use complex numbers to find solutions to quadratic equations.
