If x and y whole number such that y =19683 and `ygtx` and `1ltxlt4` then `xsqrt(y)` is _______

Prove that if 1ltxlt4 and 1ltylt4 , then |x-y|lt3

If x, y and z are whole numbers such that X>= Y , then how many solutions are possible for the equation x + y + z = 36?

Assertion : One of the rational number between (1)/(5) and (1)/(4) is (9)/(2) . Reason : If x and y are any two rational numbers such that x lt y , then (1)/(2)(x+y) is a rational number between x and y such that x lt (1)/(2) (x+y) lt y .

The number of whole number solutions of x + y + z = 20 is

If tan X = (x)/(y) , where x and y are whole numbers, then sin X is :

If (x)/(y) is a rational number, then y is always a whole number.
