How do you differentiate 5x

y=5x

The change in Y over the change in X gives the differential of 5x

As the power of 'x' is 1, this is brought down and multiplied by 5 and the power of x is 1-1 = 0. Therefore, the power of x is 0, which is equal to 1 and is multiplied by the five.

Therefore, dy/dx = 5
