Why can Sage solve one log equation, but not another with only different values?
solve(3 == 586 * 0.2 ^ x, x)
[x == log(586/3)/log(5)] // Numerical: 3.27736003989833
solve(3 == 586 * 0.99557 ^ x, x)
[100000^x == 586/3*99557^x] // Wat???
Why is it not capable of solving the second equation? Math tells us there is a solution and that it is:
log(3/586) / log(0.99557) = 1188.03958878842
