Question 940394: We need to expand logarithms but some really confuse me so I can use your help.
is log +6%2Fx+ equal to log 6 - log x? Is log +y%5E2z+ equal to 2 log y + log z? Is log +%28xy%2Fz%29%5E3+ equal to 3 log x + 3 log y - 3 log z? Because that's how I solve it. And one thing that really confuse me is how do I expand +log+3sqrt%28xy%5E2%29+ and log 225
I'm really confused and your help is much needed... I'll appreciate it if you helped me get through my problem... Thank you so much

Question 940394
I'm not sure about the 3.  Do you mean

log%283%2C%28sqrt%28xy%5E2%29%29%29 or log%28%0D%0A%0D%0A%283sqrt%28xy%5E2%29%29%0D%0A%0D%0A+++%29 or +log%28%0D%0A%0D%0A%28root%283%2Cxy%5E2%29%29%0D%0A%0D%0A%29?

Those are all different.  Tell me which one you 
mean in the thank-you note form below and I'll 
get back to you.  But whichever way you mean, 
you will change the root to a fraction exponent.
