Answer:
3a
d-5b
b^4
24ec^2x^2
Step-by-step explanation:
1. You just add all the a's.
2. Collect like terms.
(3d−2d)+(2b−7b)
Simplify.
d−5b
3. You just need to multiply all the b's together.
4. Take out the constants.
(3×2×4)ccxxe
Simplify 3×2×4 to 24
24ccxxe
Use Product Rule: x^ax^b=x^a+b
24c^2x^2e
Regroup terms.
24ec^2x^2
