27 0 obj endstream logA+logB = logAB This law tells us how to add two logarithms together. Adding logA and logB results in the logarithm of the product of A and B, that is logAB. For example, we can write log 10 5+log 10 4 = log 10 (5 4) = log 10 20 The same base, in this case 10, is used throughout the calculation.
