Tolong teman2 no 15 pleaseeeeee

limit mendekatitak hingga

lim (x->∞)  x[√(9 + 5/x) - √(9 - 4/x)] =.....kalikan x kedalam akar
lim(x->∞) √(9x² + 5x) - √(9x² - 4x)
a=p = 9
b= 5
q = - 4

limit =  (b - q) / (2 √a)
limit = (5 +4)/ (2√9) = 9/(2)(3) = 3/2

Mapel : Matematika
Kelas : XI SMA
Bab : Limit

Pembahasan :
Lim [x » ~] x[√((9 + (5/x)) - √(9 - (4/x))]
Lim [x » ~] [√(9x + 5) - √(9x - 4)]

Kalikan x kedalam akar...
Lim [x » ~] [√(9x² + 5x) - √(9x² + 4x)]

Karena a = p = 9

Maka hasilnya = (b - q)/2√a
= (5 + 4)/2.3
= 9/6
= 3/2
