## Emily778 one year ago simplify each expression X 2/3 y -1/4/ X 1/2 y -1/2

1. Emily778

|dw:1387494979971:dw|

2. Emily778

It looks like this

use the rule of exponent : a^m : a^n = a^(m-n)

4. Emily778

And by the way those numbers are squared.

5. Emily778

Can you explain it to me?

there are 2 bases there, x and y. simplify with combine them |dw:1387495189623:dw|

just evaluate : what is 2/3 - 1/2 ? and -1/4 - (-1/2 = ?

8. Emily778

I got 1 for the first one. Is that right?

9. Emily778

how ?

ah, i see you thought that 2/3 - 1/2 = (2-1)/(3-2) = 1/1 = 1, right ?

12. Emily778

yeah. :/

13. Emily778

Ugh... Can you just show me step by step on how to do this so I'm not confused?

14. SolomonZelman

Can you re-post the question? \frac{ }{ } is the latex for fraction (in equation editor)

15. Emily778

No... ._.
