Jika $f (x) = 3 x^{2}$ dan $g (x) = 5 x$ , maka $x \to a lim$ $[f (x) + g (x)]^{4} = . . . .$

$x \to a lim [3 x^{2} - 5 x]^{4}$

$[x \to a lim 3 x^{2} + x \to a lim 5 x]^{4}$

$[x \to a lim 3 x^{2} - x \to a lim 5 x]^{4}$

$[x \to a lim 5 x - x \to a lim 3 x^{2}]^{4}$

$x \to a lim [5 x - 3 x^{2}]^{4}$
