सरल कीजिए :
(i) `2^(2/3).2^(1/5)` , (ii) `(1/(3^(3)))^(7)`
(iii) `(11^(1/2))/(11^(1/4))` , (iv) `7^(1/2).8^(1/2)`

Explanation

(i) `2^(2/3).2^(1/5) = 2^((2/3+1/5))`
`= 2^(((10+3)/(15))) = 2^(13/15)`
(ii) `(1/(3^(3)))^(7) = (3^(-3))^(7) = 3^(-3xx7) = 3^(-21)`
(iii) `(11^(1/2))/(11^(1/4)) = 11^(1/2-1/4) = 11^(1/4)`
(iv) `7^(1/2). 8^(1/2) = (7xx8)^(1/2) = (56)^(1/2)`
