if log(base8)5=m and log(base4)3=n, find an expression for log(base2)15 in terms of m and n

5 = (2^3)^m = 2^(3m) 3 = (2^2)^n = 2^(2n) 15 = 2^(3m)*2*(2n) = 2^(3m+2n) log_2(15) = 3m+2n

Please show your work, and I am sure someone will "help" you (aka give you the answer that you will pass off as your own). ps Teachers ("really old people - 35-45") know all about the Internet, so if you suddenly get brilliant, they will know why.
