Please solve this Laws of Indices problem​

Answer 1

`(1)/(405)`

Explanation:

`5^{-(2)/(3) } *15^{-(1)/(3) }*3^{-(11)/(3) }` =
`5^{-(2)/(3) } *(3*5)^{-(1)/(3) }*3^{-(11)/(3) }` =
`5^{-(2)/(3) }*5^{-(1)/(3) }*3^{-(11)/(3) }*3^{-(1)/(3) }` =
`5^(-1)*3^(-4)`

`5^(-1)*3^(-4) = (1)/(5*3^(4) ) = (1)/(405)`
