Understanding the Fourth Power of Negative Numbers

The video tutorial explains how to solve the equation n = m - 3 and determine the fourth power of n - m. By subtracting m from both sides, we find n - m equals -3. The fourth power of this expression is calculated as 81, since (-3)^4 results in a positive 81. The tutorial provides a detailed breakdown of the calculation, showing how multiplying four factors of -3 results in 81.
