Question

find the value of x/y if (2/7)^-6 × (14/9)^-6 - (x/y)^-6 by stating the laws of exponents​

Answer 1

Answer:

4/9

Step-by-step explanation:

(2/7)^-6 × (14/9)^-6 = (x/y)^-6

(2/7 X 14/9)^-6 =  (x/y)^-6   [Using a ^c X b ^c = (a X b)^c]

(4/9)^-6 = (x/y)^-6

x/y = 4/9 [Powers are equal so bases are also equal]
