logb+zlogc=log( )
z logc = log c^z
since z logc = logc + logc + logc ... z times
To find the value of the expression log(b) + z * log(c) - log(x), we need more information. The expression is incomplete as the argument of the logarithm function (within the parentheses) is missing.
Once you provide the missing argument, we can proceed with evaluating the expression.
