WebJul 14, 2024 · The logarithm of a number to the base e (Euler’s constant) is known as a natural logarithm. This system was first introduced by John Napier and hence is also known as the Napierian logarithm. This type of logarithm is … WebExample: Express 3 x (2 2x) = 7(5 x) in the form a x = b. Hence, find x. Solution: Since 3 x (2 2x) = 3 x (2 2) x = (3 × 4) x = 12 x the equation becomes. 12 x = 7(5 x). Common And Natural Logarithms. We can use …
