Welcome to eBelajau Covid 19
The following topic will be covered
So when we want to solve
Problems involve law of logarithm
You need to apply the law of
location
When you solve problem involve log
So when come towards the problem
Make sure you understand the problem
These are the examples in solving
Using law of logarithm
and also problem involved
indices, surd and log
First step is to understand the problem
Find the
value of
A and
In this case find the value of T
And x
After you understand the problem you plan the strategy
And when we come to implementation of the strategy
Apply the equation given
sub the value into the equation
and finally you
Find the value of x
in this example
apply the formula given
sub the important value
finally you get the value of n
Finally you come to making conclusion
In this case when T equal to 199.8 then
x equal to 10.4 second
when x equal to 21.4567
then T equal to 1500
In another example when A equal to 1000, n = 0
A = 2000 and n = 5
When n = 15 , A = 8000
So it's time
To test your understanding, try to answer all this question
