Log and indices rules
Did you know?
WitrynaIndices are the power or exponent of a value. For example, for 32, 2 is the index and 3 is the base. Suppose, we have a value √33. This value can be written as: √33 = (33)½ = 33/2 Where 3/2 is the index. Let us solve some examples here: Example 1: 163/2 + 16-3/2 = ? We know, by laws of exponents, am x an = am+n a-m = 1/am ⇒163/2 + 1/163/2 WitrynaFrom the change of base theorem, log base a of b = (ln b)/ (ln a). For example, you can calculate log base 3 of 5 by calculating (ln 5)/ (ln 3) which should give approximately …
WitrynaWe need to carefully memorise the indices rules for: y a x y b and y a ÷ y b and (y a) b and y -a (although we memorise these, they are logical and we could work them out ourselves if we forgot them).

Example 8: log 8 ( x )+log 8 ( x ²) is the same as log 8 ( xx ²) or just log 8 ( x ³). (As you’ll see in the next section, this can be further simplified to 3 log8x.) Example 9: log 10 (20)+log 10 (50) = log 10 (20×50) = log 10 (1000) = 3.
WitrynaLaws of Logs The properties of indices can be used to show that the following rules for logarithms hold: log a x + log a y = log a (xy) log a x – log a y = log a (x/y) log a x n …
