Tutorial - Take fourth root of a negative number, cannot be simplified with real numbers

The video tutorial explains the concept of even roots and why they cannot be applied to negative numbers. It highlights that no number multiplied by itself results in a negative number, making even roots of negative numbers impossible. The tutorial briefly introduces the imaginary number system as a solution for simplifying such roots, although it is not covered in detail in this chapter.

Discuss the importance of understanding the concept of roots in mathematics.
