Hello, tdot!

I must assume you know the basic rules for exponents . . .

ok. its making more sence. i have other questions, that i tried out but wanna be sure that i have it right.

(2/x2)3 (x5)-2 (x/4)-1

(a2b3c)4 ÷ ( 3abc)2

(1+i)5 (1+i)-8

(y2/3 y1/3 y1/2) ÷ (y-6) - November 19th 2007, 10:38 PMearboth
Hello,

1. If you have a new problem start a new thread.

2. Use this sign ^ to write a power (or learn how to write in Latex)

3. Use brackets to separate bases, exponents, factors or summands.

I assume that you meant:

Transcribe this term into a product:

Expand the brackets:

= = = = = == = = = = = = = = = = = = = = = = = = = = = = = = = = =

Expand and collect like terms. I've got:

= = = = = == = = = = = = = = = = = = = = = = = = = = = = = = = = =

(y^(2/3) y^(1/3) y^(1/2)) ÷ (y^(-6)) ==>
