Question

Soal MTK limit mohon bantuannya

Answer 1

1. limit x→1 (x^3-1)^2 / (x^2 - 2x + 1) 
lim x→1 (x^6 - 2x³ + 1) / (x - 1)² 
lim x→1 (x - 1)(x - 1)(x² + x + 1)² / (x - 1)² 
lim x→1 (x - 1)²(x² + x + 1)² / (x - 1)² 
lim x→1 (x² + x + 1)² 
= (1² + 1 + 1) 
= 9

Answer 2

8.
Limx⇒-5 [x + 5] / [2x² + 9x - 5]
= Limx⇒-5 [x + 5] / [(2x - 1) (x + 5)]
= Limx⇒-5 [1] / [2x - 1]
= 1 / (2(-5) - 1)
= 1 / (-10 - 1)
= 1 / -11
= -(1/11)

9.
Limx⇒3 [x² - x - 6] / [x² - 7x + 12]
= Limx⇒3 [(x + 2) (x - 3)] / [(x - 3) (x - 4)]
= Limx⇒3 [x + 2] / [x - 4]
= (3 + 2) / (3 - 4)
= 5 / (-1)
= -5

10.
Limx⇒-5 [2x² + 9x - 5] / [4x² + 17x - 15]
= Limx⇒-5 [(2x - 1) (x + 5)] / [(4x - 3) (x + 5)]
= Limx⇒-5 [2x - 1] / [4x - 3]
= (2(-5) - 1) / (4(-5) - 3)
= (-10 - 1) / (-20 - 3)
= (-11) / (-23)
= 11/23

11.
Limx⇒0 [x³ + 2x² + 3x] / [x² - x]
= ane mumet :v maaf 3 nomer aja yak :D
