Why this function is undefined at x=0 and x=5
According to my understanding, the domain of $\sqrt{x}$ is $x \geq 0$ . If this is correct, shouldn't the domain of the function
$\frac{1}{(x^{2} - 5 x)^{1 / 4}}$
be $x \leq 0$ or $x \geq 5$ instead of x<0 or x>5? What am I getting wrong? (the answer is x<0 or x>5).
