Step 1:

\

The function is $\"\"$ .

\

Differentiate the function with respect to $\"image\"$ .

\

$\"\"$

\

Apply power rule of derivatives : $\"image\"$ .

\

$\"\"$

\

The differentiate function is $\"\"$

\

Step 2:

\

The differentiate function is $\"\"$

\

If $\"image\"$ changes by a small amount $\"\"$ this will cause $\"\"$ to change by a small amount $\"\"$ .

\

Substitute $\"\"$ in Differentiate function.

\

$\"\"$

\

Hence, the value of $\"\"$ is $\"\"$

\

Solution :

\

The value of $\"\"$ is $\"\"$

\

The value of $\"\"$ is $\"\"$

\

Step 1:

\

The function is $\"image\"$ .

\

Differentiate the function with respect to $\"image\"$ .

\

$\"image\"$

\

Apply power rule of derivatives : $\"image\"$ .

\

$\"image\"$

\

The differentiate function is $\"image\"$

\

Step 2:

\

The differentiate function is $\"image\"$

\

If $\"image\"$ changes by a small amount $\"image\"$ this will cause $\"image\"$ to change by a small amount $\"image\"$ .

\

Substitute $\"image\"$ in Differentiate function.

\

$\"image\"$

\

Hence, the value of $\"image\"$ is $\"image\"$

\

Solution :

\

The value of $\"image\"$ is $\"image\"$

\

The value of $\"image\"$ is $\"image\"$
