Answer 2

#490804/1.4641 = 335225#

base = initial base*(1 + rate of increase)^4 initial base = 490804/(1+0.1)^4 = 490804/(1.1)^4

Using Pascal triangle #(1 + .1)^4 = (1 + 4*1(0.1) + 6*1*(0.1)^2 + 4*1(0.1)^3 + (0.1)^4#
#(1+.1)^4 = 1.4641#
so that initial base = #490804/1.4641 = 335225#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
