प्रश्न

Simplify:

`(8^(1/3) xx 16^(1/3))/(32^(-1/3))`

सरल रूप दीजिए

उत्तर

`(8^(1/3) xx 16^(1/3))/(32^(- 1/3)) = ((2^3)^(1/3) xx (2^4)^(1/3))/((2^5)^(-1/3))`  ...[∵ (am)n = amn]

= `(2^(3 xx 1/3) xx 2^(4 xx 1/3))/(2^(5 xx -1/3))`  

= `(2^(3/3 + 4/3))/(2^(-5/3))`  ...`[∵ a^m/a^n = a^(m - n)]`

= `2^(7/3)/(2^(-5/3))`

= `2^(7/3 + 5/3)`

= `2^(12/3)`

= 24

= 16
