Solution:
Given Equation
y = 12/ 3^(2x)
Integral Solution
For integral solution, we need to find such values of x and y which are integers.
Manipulating the Equation
Let's manipulate the given equation:
y = 12/ 3^(2x)
3^(2x)y = 12
3^(2x)y = 3 * 2 * 2
3^(2x)y = 2^2 * 3 * 1
Factors of the Equation
Now, we need to find such values of x and y which satisfy the above equation.
Factors of 2^2 * 3 * 1 = 2, 3, 4, 6, 12
To get the value of x, we need to solve the equation 3^(2x)y = 2^2 * 3 * 1 for each factor of the equation.
Solving the Equation
For y = 2,
3^(2x) = 2^2 * 3 / y
3^(2x) = 2^2 * 3 / 2
3^(2x) = 2^1 * 3^1
3^(2x) = (3^1)^1 * (3^1)^1
3^(2x) = 3^(1+1)
2x = 2
x = 1
Therefore, (x,y) = (1,2) is a solution.
Similarly, we can solve for other factors of the equation.
