1) Use an absolute value inequality to describe te numbers that are between -6 and 8 insclusively.
-So for this problem i believe its just asking us to write down/ translate the sentence. This is what i got.
-6 < x < 8
only thing is im not sure if thats correct or if this is what im suspose to do...
2)Factor completely. x^9/5 -4x^4/5 -5x^-1/5
for this i took the smallest exponet fraction which was -1/5 and got.
-x^-1/5 (x^-9 +4x^-4 +5)
after i did this i couldnt see anything else i could do to factor it out even more. Then again im not the best with fraction exponets.....
help would be much appreciated! thanks!
