The video tutorial explains how to solve an equation involving square roots and exponents. It begins by expressing the square root of six as six to the power of one-half and 36 as six squared. The tutorial then demonstrates how to equate the exponents by multiplying them, given that the bases are the same. To clear the fraction, both sides of the equation are multiplied by two, leading to a simplified equation. The square root is then removed by squaring both sides, resulting in a linear equation. Finally, the solution for x is found by further simplification, yielding x equals 16.
