For example 2 3 8. Know the logarithm definition. So these two things are the same.
Carrying out the exponentiation can be done efficiently but the discrete logarithm is believed to be very hard to calculate in some groups.
Solving a logarithm without a calculation is easier than it might seem. Therefore 3 is the logarithm of 8 to base 2 or 3 log 2 8. Solving a logarithm without a calculation is easier than it might seem. Whenever you see a logarithm written without a base the implicit base is 10.
