Question

please solve this ..................................​

Answer 1

3^ (x-1) = 9

3^ (x-1) = 3^2

since the base is same, the powers are equal

x - 1 = 2

x = 2 + 1

x = 3

4^(y + 2) = 64

4^(y +2) = 4^3

since the base is same, the powers are equal

y + 2 = 3

y = 3 - 2

y = 1

y/x = 1/3

Answer 2

Step-by-step explanation:

so the correct answer is y/x = 1/3
