The Hardy-Weinberg law (equation) is a mathematical model in which
allele frequencies in populations remain constant from generation to
generation. Given all the conditions that must be met for the
Hardy-Weinberg equation to be valid, why is this equation useful for
studying population genetics?

It is useful because if a population breaks from Hardy-Weinberg, you know that one of the conditions are not being met. This is a convenient way to mathematically decide if natural selection is occurring.
