The video tutorial covers the proofs of the three primary laws of logarithms: the product law, the power law, and the quotient law. The instructor emphasizes the importance of understanding these proofs to sharpen skills in manipulating logarithms. Each law is explained in detail, with step-by-step demonstrations of how to derive them from basic principles. The tutorial encourages viewers to practice proving these laws independently to reinforce their understanding.
