Question

find the value of y
(12/13)^4×(13/12)^-8 = (12/13)^2y​

Answer 1

Answer: 6

Step-by-step explanation:

Points to remember :-

1) If a number has negative power, then reciprocate the number to get positive power.

E.g.  $(\frac{13}{12})^{-8} = (\frac{12}{13})^{8}$

2) If the R.H.S. and the L.H.S. have the same base, then their powers are equal.

E.g. If $(\frac{12}{13})^{12} = (\frac{12}{13})^{2y}$ then, $12 = 2y$
