whats the answer to dis one?helppppppppppppp!

3log_6 - log_6 12 + log_6 2 = ? (the base is 6)





whats the vertical asymptote, x-intercept, range and domain for this one -
log_x 4

Use the basic properties of logarithms:

log_b(xy) = log_b(x) + log_b(y)
log_b(x^y) = y log_b(x)
log_b(x/y) = log_b(x) - log_b(y)

As for the second,use

$$\log_{4}x=\frac{\ln x}{\ln 4}$$

how did u get dat?
logx4 = In x/In 4??

Saying "y= log₄ x" is the same as saying "x= 4^y". Now take the logarithm (with whatever base you want- log₁₀ or ln if you want to use a calculator): log x= log 4^{y[/sup= y log 4 so y= log x/log 4.}

^{x is the base not 4, logx4,, how oh how do u?}

What do you want to do with log_x 4? If you x is a given number, then you would find log_{x4, just as before: (log 4)/(log x). Again, the log can be either base 10 or natural log whichever is easier.}

_{find the domain, range ang x-intercept y=logx4}
