Express each of the following rational numbers with a postive exponent : `(3/4)^(-2)` (ii) `(5/4)^(-3)` (iii) `4^3x\ 4^(-9)` `{(4/3)^(-3)}^(-4)` (v) `{(3/2)^4}^(-2)`

Explanation

we have to write given rational number into negative power so,
(i)`(3/4)^-2`
`(4/3)`
(ii)`(5/4)^-3`
`(4/5)^3`
(iii)`4^3xx4^-9`
`(4/1)^3xx(4/1)^-9`
`(1/4)^-3xx(1/4)^9`
`(1/16)^-3xx9`
`(1/16)^27`
(iv)`{(4/3)^-3}^-4`
`(4/3)^-3xx-4`
`(4/3)^12`
(v)`{(3/2)^4}^-12`
`(3/2)^4xx-12`
`(3/2)^48`
