2056 x 997 = ?

0.2056 g of an organic compound gave on combustion 0.114 g of H_(2)O and 0.880 g of CO_(2_ . Find the percentage of hydrogen and carbon in the organic compound.

If f(x) = x -[x] then f(x) at x= 2 f(x) is

If the functions f(x) and g(x) are defined on R rarr R such that f(x) ={:{(0, x in " rational "),( x, x in " irrational ") :} g(x) ={:{(0, x in " irrational ") ,(x, x in " rational "):} then (f-g) (x) is

If A = { x//x is a prime number and x B = { x//2x+1, x in w and x AnnB
