Let y = 1/(2x). We want to find dy/dx (or y' depending on which notation you prefer).
To use the usual rule of 'bringing the power down and then reducing the power by 1', we will first change 1/x to x-1 (ie x to the power of -1).
y = x-1/2
dy/dx = -x-2/2 (bringing down the power of -1, and then reducing the power by 1 to get -2)
We can then remove the negative power of x by sending it to the bottom of the fraction.
dy/dx = -1/(2x-2)
Sorry to intrude dude, but you left the negative power in when sending it to the bottom, the answer should be -
dy/dx = -1/(2x2)

There is no such thing as 'Hindu maths'. Hinduism is a religion and whatever mathematics there are that are involved with it usually consist of using normal number with normal operating systems.
