Step-by-step explanation:

Put the given value to the expression.

Use PEMDAS:

PParentheses first

EExponents (ie Powers and Square Roots, etc.)

MDMultiplication and Division (left-to-right)

ASAddition and Subtraction (left-to-right)

$10.\\3m+8-2m^3,\ m=-1:\\\\3(-1)+8-2(-1)^3=-3+8-2(-1)=-3+8+2=7\\\\11.\\4y^5-6y+8y^2-1,\ y=-1:\\\\4(-1)^5-6(-1)+8(-1)^2-1=4(-1)+6+8(1)-1=-4+6+8-1=10\\\\12.\\2w+w^3-\dfrac{1}{2}w^2,\ w=2:\\\\2(2)+2^3-\dfrac{1}{2}(2^2)=4+8-\dfrac{1}{2\!\!\!\!\diagup_1}(4\!\!\!\!\diagup^2)=4+8-2=10$
