tolong dijawab beserta caranya kk

Lim (Tan 2x sin^2 8x)/(x^2 sin 4x)
= Lim (Tan 2x)/x . (Sin 8x)/x . (Sin 8x)/(sin 4x)
= 2/1 . 8/1 . 8/4
= 2 . 8 . 2
= 32

Lim (x - k)/(sin (x - k) + 2k - 2x)
= Lim (x - k) / (sin (x - k) - 2(x - k))
= Lim (x - k)/(x - k) / ((sin (x - k))/(x - k) - 2(x - k)/(x - k))
= 1/(1 - 2)
= 1/-1
= -1
