Answer:


xy^{(2)/(9)} =
x\sqrt[9]{y^2}

Step-by-step explanation:

Given


xy^{(2)/(9)}

Required

Write an equivalent expression


xy^{(2)/(9)}

Split the expression


x * y^{(2)/(9)}

Further, simplify using the following law of indices:
a^{ (m)/(n)} = a^{ m * (1)/(n)}


x * y^{(2)/(9)} becomes


x * y^{2 * (1)/(9)}

This in turn gives:


x * (y^(2)) ^{* { (1)/(9)}}

In indices:
y^{(1)/(n)} = \sqrt[n] y


x * (y^(2)) ^{* { (1)/(9)}} becomes


x * \sqrt[9]{ y^2}


x\sqrt[9]{y^2}

Hence:


xy^{(2)/(9)} =
x\sqrt[9]{y^2}
