necesito ayuda por favor ​

Answer 1

Respuesta:

lim x → 4 (√x - 2/x - 4)

lim x → 4 (√x - 2/(√x-2)(√x+2))

lim x → 4 (1/√x + 2)

lim x → 4 (1)/lim x → 4 (√x + 2)

1/lim x → 4 (√x + 2)

1/lim x → 4 (√x) + lim x → 4 (2)

1/√lim x → 4 (x) + lim x → 4 (2)

1/√lim x → 4 (x) + 2

1/√4 + 2

1/2 + 2

1/4
