I need help simplifying this problem.
it is suposed to end up as this:
but how do i get it to there? I need to see all the steps and how to get them. Thanks
your first line is good
now, do you notice x^(-1/5) and x^(4/5) ?
isn't x^(-1.5) the highest common factor ? (just like a^4 would be the HCF for a^4 and a^6)
also (x-4) is a common factor,
as well as -1/5 (pretend your first term was (5/5)x^4/5*2(x-4)
(-1/5)(x^(-1/5)(x-4)[10 + 4(x-4)]
prove that sin invers (1/5)+COT INVERSE (3)=0
