tolong bantu kerjain :'')

No. 1 skip dulu hehe
Coba dicek lagi, semoga membantu.

1) Lim (x√x - 2√x - 2√2 + x√2)/(√x - √2)
x=>2

Lim (x√x - 2√x + x√2 - 2√2)/(√x - √2)
x=>2

Lim (√x (x - 2) + √2 (x - 2)) / (√x - √2)
x=>2

Lim (x - 2)(√x + √2)/(√x - √2) . (√x + √2)/(√x + √2)
x=>2

Lim (x - 2)(√x + √2)(√x + √2) / (x - 2)
x=>2

Lim (√x + √2)(√x + √2)
x=>2

= (√2 + √2)(√2 + √2)

= (2√2)(2√2)

= 8


2) Lim (9 - x²)/[4 - √(x² + 7)]
x=>3

Lim (9 - x²)/[4 - √(x² + 7)] . [4 + √(x² + 7)]/[4 + √(x² + 7)]
x=>3

Lim (9 - x²)[4 + √(x² + 7)] / [16 - (x² + 7)]
x=>3

Lim (9 - x²)[4 + √(x² + 7)] / (9 - x²)
x=>3

Lim [4 + √(x² + 7)]
x=>3

= 4 + √(3² + 7)

= 4 + √16

= 8


3) Lim (4 - x²)/[3 - √(x² + 9)]
x=>2

Lim (4 - x²)/[3 - √(x² + 9)] . [3 + √(x² + 9)]/[3 + √(x² + 9)]
x=>2

Lim (4 - x²)[3 + √(x² + 5)] / (9 - (x² + 5))
x=>2

Lim (4 - x²)[3 + √(x² + 5)] / (4 - x²)
x=>2

Lim [3 + √(x² + 5)]
x=>2

= (3 + √(2² + 5))

= 3 + √9

= 6
