Multiply two numbers with the same base, add the exponents. The logarithm of the ratio of two quantities is the logarithm of the. Let us assume that log b x = m and log b y = n. Loga(mn) = loga m + loga n. Expand each expression (use expansion properties to expand as much as possible). Log 7 x = log y 7(x) log 7(y) (division rule). Log 3(xy) = log 3(x) + log 3(y) (multiplication rule) b. The logarithm of the product is the sum of the logarithms of the factors. Then by the definition of logarithm, x = b m and y = b n. Web the product formula of logs is, log b (xy) = log b x + log b y.
Loga(mn) = loga m + loga n. Let us assume that log b x = m and log b y = n. Expand each expression (use expansion properties to expand as much as possible). = loga x () ay = x (a; Then by the definition of logarithm, x = b m and y = b n. Web the product formula of logs is, log b (xy) = log b x + log b y. Log 3(xy) = log 3(x) + log 3(y) (multiplication rule) b. Log mn = log m + log n log 50 + log 2 = log 100 b = b 2 b think: Log 7 x = log y 7(x) log 7(y) (division rule). Web descriptions of logarithm rules. Then xy = b m × b n = b m + n (by a law of.
