निम्नलिखित घणों को प्रसारित रूप में लिखिए :
(i) ` (2x+1)^(3) " (ii) " (2a-3b)^(3)`
(iii) ` [(3)/(2)x+1]^(3) " (iv) "[x-(2)/(3)y]^(3)`

Answer

(i) `8x^(3)+12x^(2)+6x+1 " (ii) " 8a^(3)-27b^(3)-36a^(2)b+54ab^(2)`
(iii) `(27)/(8)x^(3)+(27)/(4)x^(2)+(9)/(2)x+1 " (iv) " x^(3)-(8)/(27)y^(3)-2x^(2)y+(4xy^(2))/(3)`
