## King 3 years ago I will post the question in the reply box...help....

1. King

how do i put fraction iin equation editor?this is not the question

2. experimentX

\frac{numerator}{denominator} ... in latex http://www.codecogs.com/latex/eqneditor.php

3. King

$\frac{1}{1+x ^{a-b}+x ^{b-c}} + \frac{1}{1+x ^{b-c}x ^{b-a}} + \frac{1}{1+x ^{c-b}+x ^{c-a}}$

4. King

Prove this

5. King

prove that the above is equal to 1

6. experimentX

$\frac{1}{1+x ^{a-b}+x ^{b-c}} + \frac{1}{1+x ^{b-c} + x ^{b-a}} + \frac{1}{1+x ^{c-b}+x ^{c-a}}$

7. King

yeah prove that that is equal to 1

8. experimentX

doesn't look symmetric ... are you sure this is the one?

9. King

oh sry it is a-c instead of b-c

10. ajprincess

$x^{b-a}=x ^{b}*x ^{-a}=x ^{b}/x ^{a}$

11. experimentX

My supertrick click right ... show math as => tex commands .... copy the code ... and retype the question

12. King

\frac{1}{1+x ^{a-b}+x ^{a-c}} + \frac{1}{1+x ^{b-c} + x ^{b-a}} + \frac{1}{1+x ^{c-b}+x ^{c-a}}

13. King

$\frac{1}{1+x ^{a-b}+x ^{a-c}} + \frac{1}{1+x ^{b-c} + x ^{b-a}} + \frac{1}{1+x ^{c-b}+x ^{c-a}}$

14. King

$\frac{1}{1+x ^{a-b}+x ^{a-c}} + \frac{1}{1+x ^{b-c} + x ^{b-a}} + \frac{1}{1+x ^{c-b}+x ^{c-a}} =1$

15. King

prove the above thing

16. experimentX

multiply $\frac{x^{-a}}{x^{-a}(1+x ^{a-b}+x ^{a-c})}$ do similar for others

17. King

i dont get it hw?

18. ajprincess

|dw:1339638805794:dw||dw:1339638918893:dw| Can u do the same for the others?

19. King

yeah got it!! Solved!! Thnx..@ajprincess @experimentX

20. King

Thnx... @ajprincess

21. ajprincess

U r welcome.
