Re: 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!!!

Re: Variables with Exponents - How to Multiply and Divide them
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.
I'm rambling.

How about Density. Pour milk into coffee, and some places willl have 3 times as much milk as others ...

Re: Variables with Exponents - How to Multiply and Divide them
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

Re: Variables with Exponents - How to Multiply and Divide them
Yes, maybe on another page ... what would I call the page?

Yes, density. Density is hard to think about spread out over different positions.
I've never considered that before.
