Look and learn!
\(\frac{\sqrt5+\sqrt2}{\sqrt5-\sqrt2}\)
the bottom is sqrt5 - sqrt 2
You just have to multiply both the top and the bottom by sqrt5 + sqrt2
That fact that the top is the same is just a coincidence.
That is brilliant Hectictar! Thanks!
It is going int the sticky topics. Later I might combine it in one of the other threads but for now it can stand alone and people can be referred to it :)
do you mean
\(p(x)=\frac{x+9x^2+20x+100p}{x+9}\)
That really makes little sense.......
x=-9x makes no sense either.
Very nice presentation Emerald.
Yes that is right!
What happens when you try to vote Nickolas?
Oh, I see, you already gave him a point.
Two cubes have side lengths of 3 inches and 8 inches. What is the ratio of the surface area of the small cube to the surface area of the large cube? and What is the ratio of their volumes?
sides 3:8
so surface area 3^2:8^2 which is 9:64
volume is 3^3:8^3 which is 27: 512
