I'm told that you don't need the product rule, or chain rule, or quotient rule to work it out. Can anyone show the workings as well please...?

You can take it from here using the power rule and the scalar multiple rule.
A derivative is a mathematical concept that represents the rate of change of a function at a specific point. It tells us how fast a function is changing at that point.
The derivative of a function is found by taking the limit of the difference quotient as the change in x approaches 0. In simpler terms, it is found by taking the slope of the tangent line at a specific point on the function.
The chain rule is a rule used in calculus to find the derivative of a composite function. It states that the derivative of a composite function is equal to the derivative of the outer function multiplied by the derivative of the inner function.
The derivative of a square root function is equal to 1 over 2 times the square root of the original function. In other words, it is equal to half the original function raised to the power of -1/2.
The derivative of √(2x) is equal to 1 over 2 times the square root of 2x. This can also be written as 1 over 2√(2x). In general, the derivative of √(ax) would be 1 over 2 times the square root of ax.
