1. Lim x mendekati 4 (3 + √x+5) =...... 2. Lim x mendekati 1 √x - 1 / x^4 - x =...... Tolong dibantu ya soalnya mau dikumpul pakai Cara nya ya

LImit
1.
lim (x-> 4)  (3 + √(x+5)) =
x = 4 --> lim = 3 + √(4+5) = 3 +√9 = 3 + 3  = 6

2. lim(x->1)  (√x- 1) / (x⁴ -x)
= lim (x->1)  (√x -1) / x(x³ -1)
= lim(x->1)  (√x  -1) / (x-1)(x)x²+x +1)
= lim(x->1)  (√x -1) /(√x +1)(√x-1)(x)(x²+x+1)
= lim(x->1)  1/ {(√x  +1) (x) (x² +x + 1)
x = 1 --> limit = 1 / (1+1)(1)(1+1+1) = 1/ (2)(1)(3)
limit = 1/6
