Step-by-step explanation:
The exponent of variables in a polynomial should be natural numbers (,
,
,
,
.)
is equal to
. In this expression,
is the variable. Its exponent is
, which isn't a natural number.
- On the other hand,
is equivalent to
. The exponent of variable
, which is indeed a natural number.
isn't a polynomial because the exponent of variable
isn't a natural number. On the other hand,
is indeed a polynomial over the set of real numbers.
