Answer:
x= 1.25 and y = 0.75.
Explanation:
Equation 1: (4^(2x))/(2x+y) = 32
We can rewrite 32 as 2^5:
(4^(2x))/(2x+y) = 2^5
Now, we can rewrite 4^(2x) as (2^2)^(2x) = 2^(4x):
(2^(4x))/(2x+y) = 2^5
Since the bases are equal, we can equate the exponents:
4x = 5
Dividing both sides by 4:
x = 5/4 = 1.25
Equation 2: (9^(x+y))/(3^(4y)) = 81
We can rewrite 81 as 3^4:
(9^(x+y))/(3^(4y)) = 3^4
Now, we can rewrite 9^(x+y) as (3^2)^(x+y) = 3^(2x+2y):
(3^(2x+2y))/(3^(4y)) = 3^4
Again, since the bases are equal, we equate the exponents:
2x + 2y = 4
Dividing both sides by 2:
x + y = 2
We have two equations:
x = 1.25
x + y = 2
Substituting the value of x into the second equation:
1.25 + y = 2
Subtracting 1.25 from both sides:
y = 2 - 1.25 = 0.75
Therefore, the values of x and y that satisfy the given equations are x = 1.25 and y = 0.75.
