4√7^(112/x)= 7^(112/4x) = 7^(28/x)
9√49^(45/x)= 49^(45/9x) = 7^(10/x)
Now {7^(28/x)÷7^(10/x)} = 7^(28/x-10/x)
= 7^(18/x) = R.H.S.
L.H.S. (343)^3 = (7³)³ = 7^9
Comparing both sides ,
18/x = 9
x = 2
9√49^(45/x)= 49^(45/9x) = 7^(10/x)
Now {7^(28/x)÷7^(10/x)} = 7^(28/x-10/x)
= 7^(18/x) = R.H.S.
L.H.S. (343)^3 = (7³)³ = 7^9
Comparing both sides ,
18/x = 9
x = 2
