This one went through SO MANY drafts ... how does it look to you? Variables with Exponents - How to Multiply and Divide them
The laws of exponents have been neatly presented and the graphics help in understanding the laws better. The following may be considered for inclusion on the page or a separate second page.
(a³)² = a^6
a^½ = √a
a^1/3 = cube root of a etc.
Excellent page, MathsIsFun!!!

Thanks Ganesh, and welcome back ... we have missed you!
Pretty neat at my kwik glance.
It's just too bad I can't visualize multiplying
in dimensions greater than 3 (up/down, left/right, back/toward).
Because if I could visualize blocks in 4-D like 3*3*3*3,
that would be helpful I think. I guess you could
visualize 3 cubes beside one another that are 3 by 3 by 3.

How about Density. Pour milk into coffee, and some places willl have 3 times as much milk as others ...
should you not include something on non-integer exponents, i.e. re-iterate that the addition rule doesn't just apply to integer exponents and cover things like ^0.5 = +/- square root etc or that square root is the principal root of ^0.5, the positive root. things like ^2/3 means, the cubic root, squared. for example 125^(2/3) = 5^2 = 25

Yes, maybe on another page ... what would I call the page?
