here are three problems, that may involve logarithims, please give me anything useful:
1. 4^x-2*5^(2x)<10^x
2. 7*3^(x+1)-5^(x+2)=3^(x+4)-5^(x+3)
3. 6*9^(1/x)-13*6^(1/x)+6*4^(1/x)=0

For the sake of this question we will accept that Natural Selection and Evolutionary Theory are valid. This isn't a debate about Creationism or Intelligent Design. I'm just curious about thoughts regarding this particular aspect of Natural Selection.

New traits that enhance the organism's viability are very rare, so would it be likely that the organism in question would have to be as prolific as possible in order to disseminate these new traits?

Just curious...

And another qustion which goes like this:
The sun is burning since billions of yrs. It has released tremendous amount of energy since then.According to Einstein,energy release is the result of mass lost. That means sun is continuously losing its mass since billions of yrs. According to Newton F= m1.m2/ d.d
Here the mass of the sun i.e. m2 is decreasing.And ultimately the value of F will be decreased. But still the sun is attracting the heavenly bodies with the same force..The earth and other planets have not yet left their orbits. How is this possible????How is it still balanced?????

Do you think the US Space Program will be greatly affected without the Orbiter Fleet Of Shuttles?
My Opinion- I think it will considering for almost 30 years Nasa has been having Shuttle Based missions. Plus the current space station is occasionally re-supplied by a MPLM hauled by shuttle. Lastly most Nasa Astronauts are trained to fly shuttle and Space station, so crew training will change drastically.
Whats Your Opinion

A 11.1 mL sample of a HCl solution has a pH of 2.000. What volume of water must be added to change the pH to 4.000?
mL

Yes, it can be done.

Check this: (x^2+sqrt2 x + 1)(x^2- sqrt2 x + 1)

This is obtained finding the complex root and multiplying 2 of the factors

If you have some remark, please, post them

Science students knows that the gravitational force of attraction between two objects is inversely proportinal to R*R(where R is the distance between them). But, if we have two concentric rings with different radii, there center of mass is is the same point. So, R=0 for them. Hence, the Gravitational forve of attarction should be infinite. But, in practice we can easily separate such rings. How/why?
