Exercise 1.4 | Lecture 1/2 | Cube and Fourth Roots of unity | 11th Class Math New Syllabus 2025
#newbook #maths #11thclass #chapter1

In this lecture, we begin Exercise 1.4 from the 11th Class Mathematics (New Syllabus 2025), focusing on Cube and Fourth Roots of Unity and Other Real Numbers. This lecture explains how to find cube roots and fourth roots of both unity and real numbers with clear step-by-step solutions.

You’ll learn how these roots are related to unity, their properties, and how to compute them efficiently. This lecture follows the Punjab Textbook Board (PTB) 2025 syllabus for FSc Part 1 Mathematics, making it ideal for board exam preparation.

👉 What’s Covered in This Lecture:
Concept of cube roots and fourth roots of unity
Finding cube and fourth roots of other real numbers
