The logarithmic value of any positive number, except for 1, is either above or below 0. However, log(1) is equal to 0. In the second expression, we see log(1), which is 0, along with the logs of other numbers (2, 3, 4, and 5). Using the product rule of logarithms, we can combine these logarithmic values: log(1) + log(2) + log(3) + log(4) + log(5) = log(1 2 3 4 5) = log(120). Thus, the two expressions 'log(120)' and 'log(1) + log(2) + log(3) + log(4) + log(5)' are equivalent.
