log(base 2)csc(x) = log(base 4)csc(4x^2)
I tried doing the log(base a)b = logb/loga but I can't get past that because I'm not sure what to do after that. How do I set it up so I get like cscx=? or something so I'm able to solve for multiple values of x?
the answer should be pi/3 and 5pi/3

2^(cscx) = (2^2)^[csc(4x^2)]
This requires that
cscx = 2csc(4x^2)
I don't see an easy way to solve for x.
If x = pi/3
cscx = 1.1547
2 csc(4x^2) = -2.1112
I don't agree with the pi/3 answer.
Make sure the problem is correctly stated.

Well the original problem was the following but I worked it out to what I put here before:
log(base 2)cotx - 2log(base 4)csc2x = log(base 2)cosx
I switched the cosx and the csc2x and used properties of logs to get log(base 2)cscx, but maybe I'm wrong in doing that. is there a better way to work this out from the original above?

whats the answer fro log base 5 x to the 10th power minus log base 5 x tothe 6th power is equal to 21?
