Step 1:

The function is $\"\"$ .

Apply derivative on each side with respect to $\"\"$ .

$\"\"$

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 $\"\"$
