What is value of n?

Answer is -2. How??

Thanks.
2/3)^-2 = 3/2)^2 = 9/4

3/2)^-2 = 4/9

The question should be 2/3^n = 3/2 ^ -n

Hi,
No, if the question is 2/3^n = 3/2 ^ -n, it is true for all values of 'n'.
If the question is (2/3)^n = (3/2)^n, then n=0.
Cheers!

Things are not what they appear to be... nor are they otherwise
