Question

we haven't discussed log properly yet! It's supossed to be on the RAT, but IDK. . .
this is about as much as I know:
if you have log(X) 2401 = 4, then x equals 7.

One of the simulated questions asks to express 3log(2) p + 4log(2) Q - 2log(2) R. please help.

That would be log(base 2) of
p^3 Q^4/R^2

The log of any number x to a power n is n log x, with the logs taken to the same base.
