Simplifying Radicals and Cube Roots

Mario from Mario's Math Tutoring introduces a method to simplify radicals using prime factorization. He explains the traditional method of dividing out perfect squares and its challenges. Mario then demonstrates the prime factorization method, breaking down numbers into prime factors and grouping them to simplify radicals. He provides examples with the square root of 72 and the cube root of 96, showing step-by-step simplification. The video concludes with encouragement to subscribe for more math tutorials.
