Final answer:
To simplify the expression (14x^(7)+20x^(6)-21x^(3))/(14x^(3)), divide each term in the numerator by the denominator and simplify.
Step-by-step explanation:
To simplify the expression (14x^(7)+20x^(6)-21x^(3))/(14x^(3)), we can divide each term in the numerator by the denominator. This can be .done by using the quotient rule for exponents:
(14x^(7))/(14x^(3)) + (20x^(6))/(14x^(3)) - (21x^(3))/(14x^(3))
Now, simplify each term: x^(7-3) + (10/7)x^(6-3) - (21/14)
This simplifies to: x^4 + (10/7)x^3 - (3/2)
