I tried to solve this question, but I got the conclusion that I couldn't.
Therefore I would appreciate your help
The problem is:
Let log10P = x, log10Q = y and log10R = z.
Express log10 (P/QR^3)^2 in terms of x, y and z.
"How?" . . . Have you never worked a log problem? . . . ever?
Okay, just this once . . . I'll baby-step through it for you.
Since all the logs are base-ten, I'll drop the base . . .
Express in terms of
We have: .
