Answer 1

Penjelasan dengan langkah-langkah:

LIMIT TAK HINGGA

16.

Lim [√(16x²–20x–7) – √(9x²–7x + 20) ] = ∞

x→∞

karena koefisien 16x² > 9x²

17.

Lim [√(16x²+8x–5) – (4x – 8)]

x→∞

= Lim [√(16x²+8x–5) – √(16x²–64x+64) ]

x→∞

a = 16

b = 8

c = –64

Lim [√(16x²+8x–5) – √(16x²–64x+64) ]

x→∞

= 8 – (– 64)

2√16

= 8 + 64

2 × 4

= 72

8

= 9
