50th derivative of y=cos2x. Ive seen examples but i still dont understand why 2 is being raised to a power instead of being multiplied

Question

anonymous · Answer

it is being multiplied. it is being multiplied by itself

anonymous · Answer

i found this on a different website and they posted this

f^1(x) = -1(2)^1sin(2x)
f^2(x) = -1(2)^2 cos(2x)
f^3(x) = 1(2)^3sin(2x)
f^4(x) = 1(2)^4cos(2x)

says its being raised to it? isnt the answer for the 50h derivative for y=cos2x; y=-2^50cos2x

$$-2\sin(2x)$$$$-4\cos(2x)$$$$8\sin(2x)$$$$16\cos(2x)$$...
