tolong bantuannya yg bisa a dan b make cara

a.

Lim (4x^3 + 8x / x + 4)^1/3
x→2

= (4 (2)^3 + 8(2) / 2 + 4)^1/3

= (4 . 8 + 16 / 6)^1/3

= (32 + 16 / 6)^1/3

= (48/6)^1/3

= ^3√8

= 2

.

b.

Lim (x + 2)(x² - x - 6) / x² + 4x + 4
x→-2

Lim (x + 2)(x - 3)(x + 2) / (x + 2)(x + 2)
x→-2

Lim (x - 3)
x→-2

= -2 -3

= -5
