2a+b=100 and a^b=1000?

"a" needs to be the same in the first equation as the next one. Likewise for "b".

In our dojo there are a few large excercise balls(about 2.5 ft in diameter and made from rubber) which we use to learn newcomers how to roll; however me and a few friends have tried frantically to try to lay or sit perfectly still on top of them as kind of a balance excercise. untill now noone has succeeded which has led me to believe it is impossible to do so
Am I right or am I wrong?
And why am I right or wrong?

Our small company has found use for the higher concentrations of hydrogen peroxide, specifically in the 60-70% range.

I have searched the net for days now, as we currently buy 35% and boil to higher concentrations, which is becoming much too time consuming. Not to mention, there are H2O2 losses involved with the boiling of the water.

If anyone can provide US, or international retailers of 60-70% hydrogen peroxide, it would be of great help. Thanks.
