Finding the derative of a function using the power rule

The video tutorial covers advanced examples of derivatives, focusing on expressions involving radicals and rational powers. It introduces a mnemonic for the power rule, 'bring it down, shake it down,' to help students remember the process of differentiating powers. The tutorial also revisits algebraic skills necessary for simplifying expressions to identify exponents, emphasizing the rules of rational powers.
