Multiplying and dividing composite functions I'm given:

$$f(x) = \frac{1}{x-1}$$

$$g(x) = \sqrt{\log2x}$$

I'm asked to multiply $f(x)$ and $g(x)$ and to divide them, and then state the domain for both.
Domain is x>1 because radicals have to be positive, logs can't be 0, and x cannot equal 1 or else you divide by zero which is undefined. You can simply multiply f(x) and g(x) together...here is a link if you have forgotten.
