✔ 最佳答案
A = P(1 + nr)A=P+Pnr
A-P=Pnr
.......A-P
n=----------- answer//
........Pr

A = P(1 + nr)
i.e. A = P + Pnr
i.e. Pnr = A - P
i.e. n = (A-P)/Pr
i.e. A = P + Pnr
i.e. Pnr = A - P
i.e. n = (A-P)/Pr

a = p(1 + nr)
1 + nr = a/p
nr = (a/p) - 1
n = ([a/p] - 1)/r
Answer: n = ([a/p] - 1)/r
1 + nr = a/p
nr = (a/p) - 1
n = ([a/p] - 1)/r
Answer: n = ([a/p] - 1)/r

A = P(1 + nr)
A/P = 1 + nr
nr = A/P - 1
n = (A/P - P/P)/r
n = [(A - P)/P]/r
n = [(A - P)/P][1/r]
n = (A - P)/(Pr)
A/P = 1 + nr
nr = A/P - 1
n = (A/P - P/P)/r
n = [(A - P)/P]/r
n = [(A - P)/P][1/r]
n = (A - P)/(Pr)
