28 Μαΐ 2024 · Here are some examples of conversions from exponential to logarithmic form and vice-versa. Find the value of log7(343). Solution: As we know, 7 × 7 × 7 = 7 3 = 343. Thus, log 7 (343) = 3. Convert 35 = 243 in its logarithmic form. Solution: As we know, b a = x ⇒ log b x = a. Here, 3 5 = 243. ⇒ log 3 (243) = 5, the required logarithmic form.
The logarithm of a product of two numbers is the sum of the logarithms of the individual numbers, i.e., loga mn = loga m + loga n. Note that the bases of all logs must be the same here. This resembles/is derived from the product rule of exponents: x m ⋅ x n = x m+n. Examples: log 6 = log (3 x 2) = log 3 + log 2.
Logarithm. A logarithm is the inverse function of exponentiation. A logarithm tells us the power, y, that a base, b, needs to be raised to in order to equal x. This is written as: log b (x) = y
