Why can't the variable in a polynomial have a fraction or decimal as its exponent?
Interesting. But why do we stick with whole-number exponents when working with polynomials?
One reason is that polynomials are a special type of mathematical expression that we can analyze and work with in a very structured way. By restricting the exponents to whole numbers, we can use tools like the binomial theorem and Pascal's triangle to expand and factor polynomials in a systematic way. If we allowed non-integer exponents, these tools would no longer work.
