Understanding Rational Exponents

The video tutorial explores whether the square of 2 or the cube of 3 is larger. It uses rational exponents to compare these values by converting them to a common denominator. The square of 2 is expressed as 2^(1/2) and the cube of 3 as 3^(1/3). By finding a common denominator of 6, the exponents are rewritten, allowing for a direct comparison of the bases. The tutorial concludes that the cube of 3 is greater than the square of 2.
