The population p of a species of creation after t year is given by 6(3)t-2÷2(3)t+5 where p is measured in millions.(a) what is the initial population?

Answer 1

Your notation makes no sense. 6(3)t-2÷2(3)t+5 ??
Try using more standard notation, where ^ is used for powers, and parentheses make clear how values are to be evaluated. Maybe you mean

(6t^3 - 2) ÷ (2t^3 + 5)
or
(6*3^(t-2)) ÷ (2*3^(t+5))
or something...

sometimes even just a space or two can help clarify what you mean
