lim [(x+1)^5 -1]/x
x→0
if x→0 then( x+1)→1
lim [(x+1)^5 - 1^5]/[(x+1) -1]
(x+1)→1
=5
x→0
if x→0 then( x+1)→1
lim [(x+1)^5 - 1^5]/[(x+1) -1]
(x+1)→1
=5

sorry .but i am not able to understand
if we put x=o ..then after solving we get...o/0...so we need to further evaluate that ...and i am not able to do that
lim (x^n- a^n) /(x-a)
x tends to a =n* a^(n-1) is the formula
compare the problem with the formula
ty so much....that really helped
ur welcome
