Question

1/4х3 + 3у2 при х= -2 и у= -1.

Answer 1

1/4х^3+3у^2     при        х=-2  ,у=-1
1/4*(-2)^3+3*(-1)^2=1/4(-8)+3=-2+3=1

Answer 2

To evaluate the expression 1/4х3 + 3у2 when x = -2 and y = -1, we substitute these values into the expression:

1/4(-2)^3 + 3(-1)^2

First, we need to evaluate (-2)^3, which is -8. Then we can simplify the expression as follows:

1/4(-8) + 3(-1)^2 = -2 + 3(1) = 1

Therefore, the value of the expression 1/4х3 + 3у2 when х= -2 and у= -1 is 1.
