What is x when y equals 10 in the equation y = log x?

AI Thread Summary

In the equation y = log x, when y equals 10, x can be calculated as 10 raised to the power of 10. This means x equals 10^10. The logarithm function essentially converts exponential relationships, where log x indicates the power to which the base (10) must be raised to obtain x. Therefore, the solution to the problem is x = 10,000,000,000. Understanding the definition of logarithms is crucial for solving such equations.

Hey guys I am having Problems solving this question which was given to me by a friend.

y = log x
If y = 10, then what is x?

Your help will be greatly appreciated thank you.

y=log x means 10^y=x. So, y=10 means x=10^10

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

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
