can anyone explain wha each variable emans in teh formula
K = No * e^(kt)
It ahs to do with finding the popualtion growth rate over periods of time.?

soryy i meant N = ..
not K =...

No is the the amount you started with (at time 0)
e is "Euler's number," which is a constant like pi, but has a value of about 2.718281828... (it was derived using calculus just for calculating things like this).
t is the amount of time to have passed
k is the rate of growth (or decay).
K is the number/amount after time t (basically, how much you have now).
(Note: this formula is also used for things like radioactive decay.)

e is a constant with value of approx. 2.718281828
k is the rate. If k is positive, the population is increasing. If k is negative, the population is decreasing.
No (this is probably supposed to be N(subscript 0) Which is the original population.
N is the calculated population
t is time. When t = 0, e^(kt) = e^0 =1
This will give N = No.
If t is positive, it will give the population in the future. If t is negative, it would give the population in the past.

K is your new population (after it grows/decays)
N0 is you initial population
e is the number 2.71... its like pi, but a different irrational number
k is a constant
t is time period, usually in years

Your problem isn't math, it's spelling or dyslexia.
