Радикальные выражения и рациональные показатели степени

Learn how radical expressions connect to rational exponents. Identify the index and radicand, estimate roots between integers, and simplify radicals using prime factorization, exponent rules, and absolute value when needed. Practice multiplying, dividing, adding, and subtracting radicals; convert between radical and rational-exponent notation; rationalize single-radical and binomial denominators; and divide complex numbers using conjugates. 0:00 Introduction and Radical Expressions 7:45 Estimating Radical Expressions 12:44 Simplifying Radical Expressions 21:34 Multiplying Radical Expressions 25:50 Dividing Radical Expressions 28:11 Adding and Subtracting Radical Expressions 32:31 Rational Exponents 38:00 Rationalizing Denominators 41:46 Dividing Complex Numbers
