Kakak, tolong bantuin ya..tentang turunan fungsi. Please....

bisa langsung dik
2) f(x) = 18x^7 + 12x^6
f'(x) = 126x^7 + 72x^5

3) mirip diaats... ato postkan lagi satu²...

2) f(x) = 6x^4 (3x^3 + 2x^2) = 18x^7 + 12x^6
f'(x) = 126x^6 + 72x^5

3) f(x) = (8x^1/2 - 4x^3/2) (3x^3/2 - x^1/2)
f(x) = 24x^2 - 8x - 12x^3 + 4x^2
f(x) = -12x^3 + 28x^2 - 8x
f'(x) = -36x^2 + 56x - 8
