Evaluating Cube Roots (Part 1)

This video tutorial explains how to find the cube root of a number. It introduces the cube root symbol, which is similar to the square root symbol but with a three in the upper left corner. The video differentiates between square and cube roots, explaining that the cube root of a number is the number that can be multiplied by itself three times to produce the radicand. An example is provided, calculating the cube root of 64, which is 4. The video also discusses perfect cubes and common cube roots, emphasizing that perfect cubes have whole number cube roots.
