Make "i" the subject of the formula
A=P(1+i)^n
(1+i)^n = A/P
1+i = (A/P)^(1/n)
i = (A/P)^(1/n) - 1
Make n the subject for a=p(1+1)^n
To make "i" the subject of the formula A=P(1+i)^n, we can follow these steps:
Step 1: Divide both sides of the equation by P:
A/P = (1+i)^n
Step 2: Take the nth root of both sides of the equation:
(A/P)^(1/n) = 1+i
Step 3: Subtract 1 from both sides of the equation:
(A/P)^(1/n) - 1 = i
Therefore, "i" is the subject of the formula and can be written as:
i = (A/P)^(1/n) - 1
To make "i" the subject of the formula A = P(1+i)^n, we want to isolate "i" on one side of the equation. Here's how you can do it step by step:
1. Start by dividing both sides of the equation by P: A/P = (1+i)^n
This helps us isolate the bracketed term (1+i)^n.
2. Take the n-th root of both sides of the equation: (A/P)^(1/n) = 1+i
This helps us remove the exponent n from the bracketed term.
3. Finally, subtract 1 from both sides of the equation: (A/P)^(1/n) - 1 = i
This isolates the variable "i" on one side of the equation.
Therefore, the formula with "i" as the subject is:
i = (A/P)^(1/n) - 1
