step1 =Formula for calculating compound interest:


Where,


A = final amount

P = principal amount (initial investment)

r = annual nominal interest rate (as a decimal)

n = number of times the interest is compounded per year

t = number of year 

step2

given  P= $1

r= 5%

t=300 years

n= 1 (annuly)

step2

A= 1(1+ 0.05)^300

A=  $ 2273996.129
