Answer 3

But what's the base of the logarithm you're given? Is it \[2log_{10}(20)\]

Answer 4

that's how it's written in the textbook~ 2-2log20, write as a single logarithm, but regardless, i do need help with several others

Answer 5

If it is, then \[2 = \log 100\]In which case 2-log20 is just\[\log 100 - \log 20 = \log \frac{ 100 }{ 20 } = \log 5\]

Answer 6

oh, that makes sense ^ thank you! but then how would i do 2lnx-3(lnx^2+lnx)

Answer 7

what confuses me is the -3, how do i apply that to the problem? because i know the laws and how they work, but i dont know what to do with that -3
