Hi;
how do you multiply logs ie log[base2](4) * log[base2](16) I think you work out each log seperately then multiply the solution,Is this the correct process?
Here I get 8.
Also do I do the same thing with different bases?
Thanks.
It depends, for example if you've different bases you can use:
$\displaystyle \log_a(x)\cdot \log_x(y)=\log_a(y)$
For example:
$\displaystyle \log_2(4)\cdot \log_4(16)=\log_2(16)=4$
And offcourse you can use the definition.
$\displaystyle \log_2(4)\cdot \log_4(16)=2\cdot 2=4$
Is this clear?...
