British; Español; Português easygel pretreated petri dishesWebCalculation: Given: log 2 (x + 1) - log 2 (2 - x) = 3. As we know that, log a ( x y) = log a x − log a y. ⇒ log 2 ( x + 1) − log 2 ( 2 − x) = log 2 ( x + 1 2 − x) = 3. By applying antilog on both the sides we get, ⇒ (x + 1) / (2 - x) = 2 3 = 8. ⇒ x + 1 = 8 (2 - x) ⇒ 9x = 15. ⇒ x = 5 / 3. easy gelatin salad recipeWebSolve log2(8) = x. I can solve this by converting the logarithmic statement into its equivalent exponential form, using The Relationship: log 2 (8) = x. 2 x = 8.
