anonymous 5 years ago need help finding the solution(s) to this equation..

1. anonymous

$y ^{-1}-22^{-1 \over 2}+120=0$

2. anonymous

1/y -(sqrt[22])+120 = 0 y = 1/(sqrt[22]-120)

3. anonymous

wrong 1/y -(1/(sqrt[22]))+120 = 0 1/y = (1/(sqrt(22) - 120) = (1-120*sqrt[22])/sqrt[22]) y = sqrt[22]/(1-120sqrt[22])

4. anonymous

wait, so the first thing you wrote is wrong. But this second one is right?

5. anonymous

yep

6. anonymous

oh ok, so there is only one answer? $\sqrt{22}\over 1-120\sqrt{22}$ is this correct?

7. anonymous

the line didn't show up but it's supposed to be a fraction

8. anonymous

he left :(. Polpak, does that look correct to you?

9. anonymous

Sorry, one sec

10. anonymous

$\frac{1}{y} - \frac{1}{\sqrt{22}} + 120 = 0$ $\implies \frac{1}{y} = \frac{1}{\sqrt{22}} - 120$ $\implies \frac{1}{y} = \frac{1}{\sqrt{22}} - \frac{120\sqrt{22}}{\sqrt{22}}$ $\implies \frac{1}{y} = \frac{1-120\sqrt{22}}{\sqrt{22}}$ $\implies y =\frac{\sqrt{22}}{1-120\sqrt{22}}$

11. anonymous

Yeah, that's correct

12. anonymous

can i get some help again please..

13. anonymous

the root 22 on the bottom part wouldn't type in my online assignment.. so it must not be there..

14. anonymous

Are you certain the original equation is correct?

15. anonymous

i will double check.

16. anonymous

wow. I don't know why i keep doing that..but I forgot the y.. it is all the same except there is a y after the 22

17. anonymous

$y ^{-1}-22y ^{-1 \over 2}+120=0$

18. anonymous

sorry!!

19. anonymous

Ah, that's nicer certainly.
