Law Logarithm

AI Thread Summary

The discussion centers on the implications of the logarithm cancellation law when x is 0 or lower. It is emphasized that log(x) is undefined for values of x less than or equal to 0, rendering any logarithmic laws inapplicable in such cases. Participants highlight that this fundamental property of logarithms leads to a lack of meaningful results when x is non-positive. The conversation reiterates that any mathematical operations involving logarithms must adhere to this restriction. Thus, the topic underscores the importance of understanding the domain of logarithmic functions in mathematical contexts.

Do you have an example of what you are talking about?

log(x) is undefined for x<=0, so any laws involving logs do not make sense when x<=0.

That does it. Thanks

Thread 'Finding the number of ways to arrange identical balls in a circle (3 different colors)'

I tried to combine those 2 formulas but it didn't work. I tried using another case where there are 2 red balls and 2 blue balls only so when combining the formula I got ##\frac{(4-1)!}{2!2!}=\frac{3}{2}## which does not make sense. Is there any formula to calculate cyclic permutation of identical objects or I have to do it by listing all the possibilities? Thanks

Thread 'Greatest possible value of a constant in polynomial'

Since ##px^9+q## is the factor, then ##x^9=\frac{-q}{p}## will be one of the roots. Let ##f(x)=27x^{18}+bx^9+70##, then: $$27\left(\frac{-q}{p}\right)^2+b\left(\frac{-q}{p}\right)+70=0$$ $$b=27 \frac{q}{p}+70 \frac{p}{q}$$ $$b=\frac{27q^2+70p^2}{pq}$$ From this expression, it looks like there is no greatest value of ##b## because increasing the value of ##p## and ##q## will also increase the value of ##b##. How to find the greatest value of ##b##? Thanks
