Answer:
5t vi
Vi
dy
(In(t) + 1)
dt
Step 2
Given, y =
5t vi
Taking logarithm on both sides we have,
In(y) =
In(5t vî)
→ In(y) = In(5) + Vfi. In(t)
Now differentiating with respect to t , we have
0+n(1) + Vi. +

(GIn(t) + 1)

1 dy

y dt
5t vi
Vi
dy
dt
Which doesn't match any of the options. Option-D
matches except for the first term inside the bracket. It
seems the extra 5 in (In(5t) + 1) is a typo. The
dy
5t Vi
answer must be
dt
(In(t) + 1)
Vi
