a^1/9 x a^2/3 =a^1/9 x a^6/9 =
a^7/9
(Get a common denominator and then add the exponents)

a^(1/9) * a^(2/3)
= a^(1/9 + 2/3)
= a^[1/9 + (2 * 3)/(3 * 3)]
= a^(1/9 + 6/9)
= a^(7/9)
= a^(1/9 + 2/3)
= a^[1/9 + (2 * 3)/(3 * 3)]
= a^(1/9 + 6/9)
= a^(7/9)

a^1/9 X a^2/3
= a^(1/9 + 2/3)
= a^7/9
QED
= a^(1/9 + 2/3)
= a^7/9
