Question

If 3^x-1=9 and 4^y+2=64 , find the value of y/ x- x/y​

Answer 1

Answer:

3^x-1=9

3^x-1=3²

since bases are same we can equate the powers

x-1=2

x=3

4^y+2=64

4^y+2=4³

since bases are same we can equate the powers

y+2=3

y=1

y/x-x/y=1/3-3/1

=1/3-3

=1-9/3

=-8/3

Answer 2

Answer:

-8/3

Step-by-step explanation:

3^x - 1 = 3^2 & 4^y + 2 = 4^3

x = 3, y = 1

Hence 1/3 - 3/1 = -8/3
