Question

3^x-1=9,4^y+2=64,y/x=?

Answer 1

Answer:

Step-by-step explanation:

3^x-1=3^2 =>x-1=2. =>X=3

4^y+2=4^3

=>y+2=3

=>y=1

y/x=1/3

Answer 2

Step-by-step explanation:

${3}^{x - 1} = 9$

$= {3}^{x - 1} = {3}^{2}$

when bases are same then in such cases powers are also equal

=> x-1 = 2

=> x = 3

similarly

${4}^{y + 2} = 64$

${4}^{y + 2} = {4}^{3}$

=> y+2 = 3

=> y = 1

hence y/x =1/3
