The video tutorial explains the concept of base and exponent, focusing on expressions with negative rational exponents. It demonstrates how to convert a negative exponent into a positive one and evaluates the expression 32 to the power of negative 3/5. The tutorial also covers how to express a rational exponent as a radical and calculates the final value of the expression.
