Test: Limits Of Rational Functions - Question 6

The value of the limit  

Detailed Solution for Test: Limits Of Rational Functions - Question 6

lim x → 2 [(2x - 4) (2x - 2) ((√2x) + 2)]/[(√2x - 2) (√2x - 2)]
= lim x → 2 [(2x - 4) (2 *4)]/(√2x - 2)
= 2 lim(x → 2) [(√2x)2 - (2)2]/(√2x - 2)
= 2 lim(x → 2) [(√2x)2 + 2) (√2x)2 - 2)]/(√2x - 2)
= 8

Test: Limits Of Rational Functions - Question 8

The value of the limit

 

Test: Limits Of Rational Functions - Question 9

Detailed Solution for Test: Limits Of Rational Functions - Question 9

Test: Limits Of Rational Functions - Question 10

Detailed Solution for Test: Limits Of Rational Functions - Question 10

 limx→1x9−1/x5−1 has indeterminate initial form (it has form 0/0). Therefore 1is a zero and x−1 a factor of both the numerator and the denominator.
limx→1 x10−1/x5−1
= limx→1[(x−1)(x8+x7+x4….⋅+x+1)]/(x−1)(x5+x6+x4+⋅⋅⋅+x+1)
= (1+1+1+1+.....upto 10 terms)/(1+1+1+⋅⋅⋅upto 5 terms)
= 10/5 = 2
