WebLogarithms Definition : For any number y such that y a=x ( a >0 and a ≠1), the logarithm of y to the base a is defined to be x and is denoted by log a y. Thus if y a=x, then log a y x= For example, 81 3=4 ∴ =log 81 43 100 10= 2 ∴ =log 100 210 Note: The logarithm of 1 to any base is 0, i.e. log 1 0a =.

Web9 aug. 2016 · With the above expressions, we can say that logarithms and indices are inter-related. Laws of Logarithms. These are similar to all the laws of indices. It shows clearly that a logarithm is a mirror image of an index. e.g. 100 = 10 2; 2 = log 10 100. 1000 = 10 3; 3 = log 10 1000. 0.01 = 10-2; -2 = log 10 0.01. Evaluate the following: (1) If. 1 ... WebFrom the definition of a logarithm, prove that log a 1 log x x a =. Hence, or otherwise, solve the equation : 6 13 x 8 log 8 log x + =. 15. If loga n = x and logc n = y where n ≠ 1, prove that log c log a log c log a x y x y b b b b + − = + −. Verify this result, without using calculators , when a = 4, b = 2, c = 8 and n = 4096 . 16. WebLogarithms are classified according to the value of their base. Essentially, there are two (or three) types. a) Common Logarithm: This is a logarithm to the base of 10, i.. In general, when the base is 10, it is usually omitted. In other words, is simply written as . Common logarithm is also called Briggsian named after Henry Briggs. suppose 1.80 mol of an ideal gas is taken
