How to find the derivative of a root?<span>Use the rule to differentiate the following example, first simplifying the root and writing it as a fraction using the notation. Move 7/6 forward then decrease the power by 1. Use the definition of a derivative to differentiate f(x) = x^–1 = 1/x. First simplify the numerator then simplify and cancel as much as possible.</span>
Answer:2.634 in./s
Step-by-step explanation:
Given
Length (L)=18 in.
width (B)=12 in.
height(h)=4 in.
Volume of water is increasing at a rate of 569 
Volume of a box is given by=LBh
and 
as L&B are constant therefore


Here is your solution,
(-5)^2 - √25 - 4 x (-14)/2
25 - √ 25 + 56/2
25 - √81/2
(25 - 9)/2 = 16/2 = 8
or
25 + √25 +56/2
25 + √81/2
(25 + 9)/2 = 34/2 = 17
So m = 8,17
48/5 or 9 3/5
12.8/1 x 3/4 = 38.4/4
Or multiply 12.8/1 by 10 ==> 128/10
128/10 x 3/4 = 384/40
Hope this helps!
