about exponentials and logarithmic function
i was study harder to learnt this subject.i was in lucky because my friend was helping me to understand this subject.Hopefully i will not forget the step how to solve the question in the second test after raya break.however i wass making mistakes in the quiz that had i throught.The mistaken was give me a lesson to not doing a same mistake in future.xh
exponential and logarithmic functions
exponential and radical:
>a repeaters multiplication can be represented by notation.
example of notation :
a^n=a is a real number,n is the positve integers
the notation represent to a repeaters ultiplication of a.
a^-n=that means the notation becomes to 1/a^n.
the theorem of exponentials:
(a^m).(a^n)=a^m+n >product rules
(a^m)^n=a^(m.n) >power of power rules
a^m/a^n=a^m-n >quetient rule for exponents
(ab)^m =(a^m)(b^m) >power of product rule
(a/b)^m=a^m/b^m >power of quotient rule
logarithmic function involves :
>involves of changed of base,
>logarithm notation,and
>logarithmic function and graph.
>logarithmic and exponential equations
