<em>Task</em>: To find the derivative of 1/rootx
<em>Rewrite</em>: To find the derivative of the function 1 / 
To find the derivative, follow these steps:
<em>(i) Rewrite the function as</em>
=> 
<em>Remember that </em>
<em> can be written as </em>
<em />
=> 
=>
<em />
<em />
<em>(ii) Multiply the coefficient of </em>
<em> by the power of </em>
<em />
Coefficient of
<em> </em>= 1
Power of
<em> </em>= 
=> (
x 1)
<em />
=> (
)
<em />
=>
<em />
<em />
<em>(iii) Subtract 1 from the power of </em>
<em />
=>
<em />
=>
<em />
Therefore, the derivative of 1/root x is
