A curve has the equation y=12+3x^4. Find dy/dx.

Bring the power down and multiply it to the value directly before x, and then remove 1 from the power after this. So in this instance 12 has no x or power with it, therefore it disappears because you multiple it by 0. and the 3 is now multiplied by 4 to leave y=12x^3.
