Question : 61 of 100

Marks: +1, -0

If

(x / y )^{a-4} = (y / x )^{2a-5}

, then what is the relation between x and y ?

x > y
Cannot be determined
x < y
x = y

Solution:

(x / y )^{a-4} = (y / x )^{2a-5}

⇒

(x )^{a-4}/ (y )^{a-4} = (y)^{2a-5} / (x )^{2a-5}

⇒

x^{a-4+2a-5} = y^{a-4+2a-5}

⇒

x ^{3 a - 9} = y^{3a -9}

∴ x = y
