    To multiple powers you add them 2/5+2/9 = 18/45+10/45=28/45 x^(18/45) https://answers.yahoo.com/question/index?qid=20150209154454AAwfqUk

    \[x^\frac{ 2 }{ 5}\ \times\ x^\frac{ 2 }{ 9}= x^(\frac{ 2}{5}+\frac{ 2 }{ 9 })\\=x^\frac{ 28 }{ 45}\]

    @Elsa213 x^(28/45) not x^(18/45). common mistake in arithmetic operations.
