WebWhen adding two logarithms, in the same base b, the following simplification can always be made: logb(a) + logb(c) = logb(a × c) Example The expression: log3(5) + log3(8) can be simplied and written: log3(5) + log3(8) = log3(5 × 8) … WebLogarithm Formula Mathematics Doubts. In mathematics, logarithms are another way of writing exponents. The logarithm of a number with a base is equal to other numbers. The logarithm is just the opposite function of exponentiation. For e.g, if 10 2 = 100, then log 10 100 = 2. Log b x = n or b n = x. Where b = base of the logarithmic function. WebThe four basic laws of logarithms include: The Product Rule Law The first law of logarithms state that the sum of two logarithms is equal to the product of the logarithms. The first law is represented as; log A + log B = log AB Example: log 2 5 + log 2 4 = log 2 (5 × 4) = log 2 20 log 10 6 + log 10 3 = log 10 (6 x 3) = log 10 18 gretna weather
