WebDefine and use the quotient and power rules for logarithms. For quotients, we have a similar rule for logarithms. Recall that we use the quotient rule of exponents to simplify division of like bases raised to powers by subtracting the exponents: xa xb = xa−b x a x b = x a − b. The quotient rule for logarithms says that the logarithm of a ... Web1 Dec 2024 · Roughly a century ago, some engineers at Bell Labs began using logarithms for expressing power losses in transmission lines. The essential advantage of using a logarithmic scale for power losses was that cumulative power losses could be readily totaled using addition instead of multiplication.
