" (ii) "7a^(3)+56b^(3)

The value of 2a^(3)-[3a^(3)+4b^(3)-{2a^(3)+(-7a^(3))}5a^(3)-7b^(3)] is (a) -11a^(3)+3b^(3)( b) 7b^(3)+3a^(3)(c)11a^(3)-3b^(3) (d) (11a^(3)+3b^(3))

Find the following products: 2a^3(3a+5b) (ii) -11 a(3a+2b) (iii) -5a(7a-2b)

Find the following products: 2a^(3)(3a+5b) (ii) -11a(3a+2b)-5a(7a-2b)( iv) -11y^(2)(3y+7)

If a^(3) =1+7, 3^(3) = 1+7+b, 4^(3) = 1+7 +c , then the value of a+ b+ c is

If   a : b = 7 : 3 , then find ( a^3 - b^3 ) /b^3

If (3a+7b)/(3a-7b)=(4)/(3) then find the value of the ratio (3a^(2)-7b^(2))/(3a^(2)+7b^(2))
