Witryna29 mar 2024 · It states that the logarithm of a power number can be obtained by multiplying the logarithm of the number by that number. Sample Problems. Problem 1: Expand log 21. Solution: As we know that log x ab = log x a + log x b (From first law of logarithm) So, log 21 = log (3 × 7) = log 3 + log 7. Problem 2: Expand log (125/64). … WitrynaSet each factor equal to zero then solve for x x. x x as potential solutions. Make sure that you check the potential answers from the original logarithmic equation. You should agree that \color {blue}x=-32 x = −32 is the only solution. That makes \color {red}x=4 x = 4 an extraneous solution, so disregard it.
WitrynaFollowing rules needed to be remembered while playing with logarithms: Given that a n = b ⇔ log a b = n, the logarithm of the number b is only defined for positive real numbers. a > 0 (a ≠ 1), a n > 0. The logarithm of a positive real number can be negative, zero or positive. Examples. 3 2 = 9 ⇔ log 3 9 = 2. 5 4 = 625 ⇔ log 5 625 = 4. Witryna30 sty 2024 · The pH scale is logarithmic, meaning that an increase or decrease of an integer value changes the concentration by a tenfold. For example, a pH of 3 is ten times more acidic than a pH of 4. Likewise, a pH of 3 is one hundred times more acidic than a pH of 5. Similarly a pH of 11 is ten times more basic than a pH of 10.
