Question

someone mind walking me through this?
not sure how this was done...

see attached.

Answer 1

Is this math? Calculus possibly?

Answer 2

deriving from dimensional analysis (physics), but this part is just algebra

Answer 3

I haven't got to that yet in physics, but I am wondering if it's using logs to get those x and y exponents down into a "numerical" setting.

Answer 4

I get where the 1 comes from i guess
if s = 1
then it becomes
\[1 = m^x m^y \]
but even with taking the ln of each sides, we still have an unknown ln m

Answer 5

That is true. Yeah I tried doing that in my head and I am kinda confused. @dan815 or @Owlcoffee ? Suggestions?
