Understanding Exponential Equations

The video explores whether a given equation can be true. Initially, it seems incorrect, but the teacher breaks down the equation by rewriting 8 as 2 cubed and simplifying it through multiplication of exponents. Despite the result not equaling 91, the teacher demonstrates how the equation can be adjusted to become true, showing that 16 equals eight plus eight.
