If ln y = (ln x)2 + 2, then find dy / dx in terms of x and y.

 The required value of is

Step-by-step explanation:   We are given to find the value of from the following equation :

Differentiating both sides of equation (i) with respect to x, we have

Thus, the required value of in terms of x and y is .

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
