Answer 2

Step-by-step explanation:

In this question,. (49/25)^-6 can be written as

==> (25/49)^6 which can also be written as (5/7)^12 since 25 = 5^2 and 49 = 7^2

==> (5/7)^3 × ( 5/7)^12 = (x/y)^15

==> (5/7)^15 = (x/y)^1

==> (x/y) = (5/7)^-3

==> (x/y)^-3 = 343/125

Important things to remember about exponents

a^m × a^n = a^m+n

(a^m)^n = a^mn

a^0 = 1
