A population of bacteria is growing according to the equation
P(t)=1950e^0.07t. Estimate when the population will exceed 3010.
~~~~~~~~~~~~~~~~~~

Write inequality

    3010 < .


Divide both sides by 1950

     < ,


which is the same as

     < .


Take logarithm base 10 of both sides

    log(1.543589744) < 0.07*t.


Express t and calculate

    t >  = 2.693312634.


Round with 4 decimals  t = 2.6933.    ANSWER


The problem does not provide the name of the time units,
so I can not name the unit of the time in my answer.

Solved.

What you see in my post, is a standard procedure for solving such problems.
