evaluate -(11/17^-10/(9/5)^(1/10)
answer from Reiny:
(-11/-17)^-10
= 1/(11/17)^10 = 77.725... (I stored that in A on my calculator)
(9/5)^(1/10) = 1.0605..
so -(11/17^-10/(9/5)^(1/10)
= -77.725... /1.0605...
= -73.28837824

do we need to reciprocal -(11/17) to -(17/11) ?
You must be referring to the post from yesterday
where you had
-( -11/-17)^-10 ÷ (9/5)^(1/10)
http://www.jiskha.com/display.cgi?id=1423540960yes , you could have done that.
I treated the (-11/-17)^-10
as 1/(11/17)^10 which was 77.725...
You want to do (17/11)^10 which is also 77.825..
Of yourse you can do that
remember that (a/b)^-n = 1/(a/b)^n or (b/a)^n
same thing
and of course (9/5)^(1/10) = 1.06054... , like I had
so -( -11/-17)^-10 ÷ (9/5)^(1/10)
= -(77.725..)/(1.06054...)
= - 73.28837824
I stand by my answer.
now you mention,yes I could have paste the link but i didn't think of it, SORRY!
Thank You very much!
