Question 979323: Hello
The lessons is about extracting the roots so i don't know if in the right one
But anyway hope you can help me solve this problem :)
Thank you!
When the amount of (p) is invested at the annual interest rate (r) compounded for (t) years, it will grow to an amount (a) given by the formula
A=P (1+r)^t
1find the interest rate if php 30,000 compounded annually grows to php 33,765 in four years?
2 find the interest rate if php 50,000 compounded annually grows to php 55,204 in five years?
Hope anyone can solve this :)

1find the interest rate if php 30,000 compounded annually grows to php 33,765 in four years?
33765 = 10000*(1+r)^4
(1+r)^4 = 3.3765

1+r =~ 1.35555
r = 0.3555 = 35.55% per year
