Question

СРОЧНО ДАЮ 72 БАЛА!!!!!!!!!!!!!!!!!!!!!

Answer 1

а) у'(х)=((5х^4+3х^2+1)(х+1)-(х^5+х^3+х))/(х+1)^2=(5х^5+5х^4+3х^3+3х^2+х+1-х^5-х^3-х)/(х+1)^2=(4х^5+5х^4+2х^3+3х^2+1)/(х+1)^2
у'(1)=(4+5+2+3+1)/(1+1)^2=15/4=3,75

б) у'(х)=(2х×/(х) - (х^2-4)/(2/(х))/х=(4х^2-х^2+4)/(2х×/(х))
у'(1)=(4-1+4)/(2×1)=7/2=3,5
