Final answer:
To simplify the expressions by using only positive exponents, we need to follow the rule that any term with a negative exponent can be moved to the denominator with a positive exponent.
Step-by-step explanation:
To simplify the expressions by using only positive exponents, we need to follow the rule that states any term with a negative exponent can be moved to the denominator with a positive exponent. Let's simplify each expression:
- A) 2x^9v^3w^4: This expression is already in simplified form with positive exponents.
- B) 24x^12v^3w^4: We can rewrite 24 as 2x^12 and simplify to get 2x^12x^12v^3w^4 = 2x^24v^3w^4.
- C) x^12v^3w^4: This expression is already in simplified form with positive exponents.
- D) 2x^9v^3w: This expression is already in simplified form with positive exponents.
