:?: i need help with the properties of logs and how to work them with problems
such as:
logx(2)=.05
log8(0)=x
logx(64)=4
log4(16)=x
logx(8)=3

I need as much information as possible as soon as possible!!!!
 
Your formatting is ambiguous. For instance, do you mean the expression after "log" and before the parentheses to be the base? So the first equation would be "log<sub>x</sub>(2) = 0.05"? And would the instructions be to "solve"?

If so, then most of the exercises look like "convert to the exponential form" sorts. For instance:

. . . . .Solve: log<sub>5</sub>(x) = 2

. . . . ."log<sub>5</sub>(x) = 2" means 5<sup>2</sup> = x, so x = 25.

. . . . .Solve: log<sub>x</sub>(64) = 3

. . . . ."log<sub>x</sub>(64) = 3" means x<sup>3</sup> = 64 = 4<sup>3</sup>, so x = 4.

Follow this process with your examples.
