The step which is necessary in verifying that lnB + 3 = −3t is a solution to dB/dt = -3B is differentiate the function.

### What is differentiation?

In mathematics, differentiation is the process of determining the derivative, meaning rate of change, of such a function.
• In contrast to the abstract character of the theory that underpins it, the actual methodology of differentiation can be performed out using solely algebraic manipulations, employing three basic derivatives, 4 rules of operation, and understanding of how to operate functions.
• The chain rule takes the more memorable “symbolic cancellation” form in the German mathematician Gottfried Wilhelm Leibniz’s notation, which utilizes d/dx in place of D and so permits differentiation with respect to distinct variables to be made explicit: d(f(g(x)))/dx = df/dg dg/dx.
Now according to the question; the given function is ;
lnB + 3 = −3t
Differentiate the function with respect to t;
(1/B)(dB/dt) + 0 = -3
Further simplifying;
(dB/dt) = -3B which is the requites solution for the function.
Therefore, to solve the given function differentiation is needed to be done.
