Given p>0, prove p +1/p >= 2 I hate of these proving questions (but the process of solving them is quite fun, I just hate them cos I can't get them right :( )

you might wanna post this thread in the HSC forum since you can find most of the (no offence, more experienced and on average, smarter) y12's on there who can help you more

These questions have my brain tied in a knot, but I THINK the answer to the second one is 27n*36n-2 Edit: I'm hopeless at maths, ignore this :(

ok Yeah I should write francium based on what I've learnt from school (and on here) instead of some magazine whilst waiting at a haircut place. I hope we do radioactivity in depth in year 12 though

eat a dick Shouldn't you be studying for Studies of Religion?

Francium's radioactivity hinders it from being the least electronegative metal (so Caesium's the most electronegative), so I'm assuming this also hinders it from being the most reactive as well since Caesium is not radioactive. Francium is still one of the most reactive metals though

Non metals: Fluorine Metals: Caesium
