Actual title of this thread is Logarithmic problems, sorry.

Anyway. I don't know how to use subscript, but any help/explanations would be grand. (note that in the first problem, there is nothing that is in subscript.)

"Evaluate the problem: log4 + 2log5"

"Solve the equation: log5x-3log52=log53"

-----------------

Also, "Solve the equation: logx32= 5"

But as for this one, I tried and got as far as this:

x^5 = 32
