2. arindameducationusc

yes @Vocaloid

3. yamyam70

correct

4. anonymous

|dw:1440263297887:dw|

5. anonymous

so that's right?

6. arindameducationusc

yup

7. anonymous

but the answer says it's just 25...

8. Nnesha

1/1 is 1 right ?

9. anonymous

yea..

10. Nnesha

$\huge\rm \frac{ \frac{ 1 }{ 1 } }{ \frac{ 1 }{ 25 } } =\frac{ 1 }{ \frac{ 1 }{ 25 }}$

11. anonymous

oh.... I see so solve numerator first ?

12. Nnesha

$now change division to multiplication you can divide 1 over 1 =1 13. Nnesha yes right solve the numerator 14. arindameducationusc Oops yes @Nnesha is right! 15. Plasmataco It's just 25. 16. anonymous okay got it thanks Nnesha! 17. arindameducationusc Sorry about that, mistakes do happen! 18. Plasmataco Yes, like that 19. Nnesha my pleasure :=) 20. Nnesha @arindameducationusc yes right i do all d e time 100 mistakes every day 21. Nnesha :P 22. arindameducationusc No worries then! hehe :) 23. anonymous wait sorry come back 24. anonymous |dw:1440263762465:dw| 25. anonymous The negative exponent tho... 26. phi Yes, you get 1/25 if the book says otherwise, it is a mistake. 27. phi \[ \huge\rm \frac{ \frac{ 1 }{ 1 } }{ \frac{ 1 }{ 25 } } =\frac{ 1 }{ \frac{ 1 }{ 25 }}$ that is true but the question starts with $\frac{ \frac{ 1 }{ 1 } }{ \frac{ 1 }{ 5^{-2} } }$

28. Nnesha

$\frac{ \frac{ 1 }{ 1} }{ \frac{ 1 }{ 5^{-2} }} = \frac{ \frac{ 1 }{ 1 } }{ \frac{ 5^2 }{ 1 } }$ flip the fraction to get positive exponent

29. anonymous

Wouldnt you still get 1 over 25 Nnesha?

30. Nnesha

$\huge\rm \frac{ \frac{ 1 }{ 1 } }{ \frac{ 5^2 }{ 1 } }$ now change division to muliplication

31. Nnesha

yes right $\huge\rm \frac{ 1 }{ 1 } \times \color{Red}{\frac{ 1 }{ 5^2}}$

32. Nnesha

i messed up i guess hmm let me see

33. Nnesha

ahh the negative exponent i thought it is positive..

34. anonymous

No it's negative

35. Nnesha

yes then 1/25 is right you must need to flip the denominator fraction

36. anonymous

hmmm okay so i guess my book is wrong this is weird because they laid out a detailed explanation

37. Nnesha

whats the ansswer in the book ?

38. anonymous

it says it's 25

39. Nnesha

u sure ?? :P weird maybe you are lookin at the wrong question hmm

40. anonymous

but they do it weird in the solutions it has this |dw:1440264371674:dw|

41. anonymous

they have the long line in the wrong place

42. anonymous

maybe thats why they messed up

43. Nnesha

lol can you take a screenshot ?

44. anonymous

okay hang on

45. Nnesha

:)

46. anonymous

47. anonymous

there you go

$$\color{blue}{\text{Originally Posted by}}$$ @Nnesha $\frac{ \frac{ 1 }{ 1} }{ \frac{ 1 }{ 5^{-2} }} = \frac{ \frac{ 1 }{ 1 } }{ \frac{ 5^2 }{ 1 } }$ flip the fraction to get positive exponent $$\color{blue}{\text{End of Quote}}$$ this is right then

50. Nnesha

1/1 top fraction 1/5^{-2} fraction at the denomiantor

51. anonymous

so its 1/25 right? the solution in the book is wrong

52. Nnesha

yes right it's 1/25 $\huge\rm \frac{ \color{reD}{\frac{ 1 }{ 1 }} }{ \color{blue}{\frac{ 1 }{ 5^{-2}} }}$ =$\huge\rm \frac{ \color{ReD}{1} }{\color{blue}{ 5^2} }$

53. anonymous

okay haha i knew the book was wrong ! thanks!!

54. Nnesha

np.-. i'll be glad if you give arindameducationusc da medal :)
