How do you solve 3log plus logy minus 2logz equal to?

Answer 1

Since there's no "equals" sign there ( = ), there's no equation, and nothing to solve yet.

All you have so far is a number. There's no way to determine what the number is

until you know the values of 'x', 'y', and 'z'. If you know those, then the number

is found like this:

-- Calculate or look up the log of 'x'. Triple it, and put that number aside.

-- Calculate or look up the log of 'y'. Put it aside.

-- Calculate or look up the log of 'z'. Double it, and put that number aside.

Now you have three numbers put aside.

-- Add the first and second ones, then subtract the third one.

The result is the complete numerical value of the expression in the question.
