In this lesson on Rational Exponents, the instructor demonstrates how to convert expressions with radicals and fractional exponents into single rational expressions. By adding and subtracting exponents with the same bases, the instructor simplifies the expressions and writes them as single radical expressions. Even when the bases are different, the instructor shows how to find a common denominator to combine the expressions into one radical expression. The lesson concludes with an example of combining three different radicals with different denominators by finding a common denominator and writing the expression as one big radical.
Part 5 shows examples working with radicals and fractional exponents.
