Answer:
Only natural numbers (i.e., non-negative integers) can be the exponents of variables in a polynomial.
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 is , 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.

Answer:
21120
Step-by-step explanation:
1 mile = 5280 feet
5280 feet * 4 = 21120
I believe that x=9. I used cross multiplication. First, I multiplied 6 by 15. Second, I divided this product of 90 by 10. The quotient is 9.
