Understanding Exponent Properties and Simplification

The video tutorial guides viewers through solving a complex power calculation without a calculator. It begins by introducing the problem of calculating 256 to the 47th power divided by 2 to the 47th power. The instructor explains how to use exponent properties to simplify the expression, eventually reducing it to a simpler form. By recognizing 128 as a power of two, the problem is further simplified, leading to the final calculation of 2 to the 4th power, which equals 16. The tutorial emphasizes understanding exponent properties and recognizing patterns in powers of numbers.
