If you dont follow the right steps in the right order or properly, you won't end up with the right answer:
For example 3 x 5 + 7
If you do multiplication then add you get 22 which is correct.... but!!
If you add then do multiplication you get 36 which isn't right

Remember always follow PEMDAS
P-Parenthesis
E-Exponents
M or D- Multiplication or division (go left to right)
A or S- Addition or Subtraction (go left to right)

We're told x=-5 and y=11 and asked to evaluate a few expressions. That just means substitute these values into the expressions and compute the exact numerical answer.

4y-10x = 4(11) - 10(-5) = 44 + 50 = 94

Answer: 94

x to the power of 3

x^3 = (-5)^3 = -5 \times -5 \times -5 = -125

Answer: -125

•6y to the power of 2

Probably means

6y^2 = 6(11)^2 = 6(121) = 726

Answer: 726

5(3x+2y) = 5(3(-5) + 2(11)) = 5(-15 + 22) = 5(7) = 35

Answer: 35

•(y-x) to the power of 2

(y - x)^2 = (11 - -5)^2 = 16^2 = 256

Answer: 256
