Why should power of variable and the variable itself should be a whole number not a natural number.
why should a variable have a exponent which is a whole number, to be called as polynomial? why can't the exponent be fraction like x1/2 or negative number like x-2?
Why can the variable be raisesd only to a whole number? Why can't it be raised to any real no.s?
Solution of all one variable linear equation should be rational number.
