Question

lim x^m -1/x^n -1
x → 1

Answer 1

Answer:

lim x->1 (x^m-1)/(x^n-1)

using Leibniz rule

= limx->1 (mx^(m-1))/ (nx^(n-1))

put x= 1

=m*(1)^(m-1) / n*(1)^(n-1)

= m/n

Answer 2

Answer:

LIM x>1(x^m-1)/(x^n-1)

USING LEBENIZ RULE

=limx->1(mx^(m-1))/nx^(n-1))

PUT x=1

=m*(1)^(m-1)/n*(1)^(n-1)

=m/n
