<u>I'm very sorry but i don't know the answer to this queshtion</u>
14^(7x) = 17^(-8-x)
Take the log of both sides:
7x*log 14 = -(8+x)*log 17, or 7x^log 14 = -8*log 17 - x*log 17.
Grouping the x terms, we get x(7*log 14 + log 17)= -8*log 17
Then:
-8*log 17
x= -------------------------- (answer)
7*log 14 + log 17
B,C and D are correct because all of those choices include letters which are arranged in order from left of right.
Look at the picture. I have no idea why I can't add an answer.
