Solve c2 = c1(q2/q1)^x for x, assuming c1, c2, q1, q2 are known

[pippo]

Hi guys, sorry been struggling with this for ages now and cant get close.

i want to find x in the following equation given all others are known.

c2 = c1(q2/q1)^x

Thanks

… been struggling with this for ages …

c2 = c1(q2/q1)^x

What did you try?

I would isolate (q2/q1)^x, before using logarithms.

If you want to leave x by itself, just use log.

log_(q2/q1) (c2/c1) = x
