Simplify each expression
Amiraneli [1.4K]
1. -4+5x^3-(-3y)^0

-1+-3=-4
3x^2+ 2x^1= 5x^3
9y^1-6y^1=14y^0

2. 2y-(-3x^5)+10

5y-3y=2y
-3x^1+-2x^2=-5x^3
-5x^3+2x^2=-3x^5

3. 3x+3y+8

4x^2+2x=6x^3
6x^3-3x^2=3x
7y-2y=4y
4y-y=3y
-5+(-3)=8

4. 6x^3+4y+2

3x^2+3x^1=6x^3
7y-2y=5y
5y-y=4y

I hope this helped
