Roots and Solutions of Equations

The video tutorial explains how to find the indicated real nth roots of a number. It covers the basic setup of the problem, where a number X raised to the power of N equals A. The tutorial discusses the difference between even and odd exponents, providing examples for each case. Special cases, such as when the result is zero or involves negative numbers, are also addressed. The video concludes with a discussion on imaginary solutions when dealing with negative numbers under even roots.
