The logarithm of any positive number n to the base b is the power l to which that base must be raised in order to satisfy the identity n = b l : l = log b n. Logarithms to the base 10 are called common logarithms and written log or log 10 . Logarithms to the base e = 2.7182818284 . . . are called natural (Napierian, hyperbolic) logarithms, and are often written log e or ln. The natural logarithms are the more convenient in any computations involving differentiation

We call the b positive number's a based (a > 0; a cannot equal with 1) logarithm that exponent, which we get, if we raise a to the b th power. Symbol: a^log a b = b; The natural logarithm: 10^lg b = b (The ^ sign means raising to a higher power)

| logarithm |
formally, the number of times ten must be multiplied with itself to equal a certain number. For example, log 5 is 100,000 (10 x 10 x 10 x 10 x 10). VIRAL LOAD is often reported in terms of log. In addition, logs are used to measure changes in viral load. For example, a reduction in viral load from 100,000 to 1,000 copies/ml is a 2.0 log (or 99 percent) reduction (100,000 divided by 100 [2.0 log or 10 x 10] equals 1,000). ...
