Exploring Perfect Squares and Square Roots

The video tutorial discusses rational numbers, focusing on perfect squares and powers. It explains how multiplying a number by itself results in a perfect square, using examples from 1 squared to 6 squared. The concept of square roots is introduced as the reverse process of squaring, emphasizing that perfect squares have whole number square roots, making them rational numbers. This understanding sets the stage for future discussions on irrational numbers.
