Question

-1^3+(-2)^2 ??????????

Answer 1

=-1+4=3.................

Answer 2

-1³+(-2)²=-1+4=3...........

Answer 3

Let's calculate the expression step by step:

-1^3 + (-2)^2

First, let's evaluate -1^3: -1^3 = -(1^3) = -(1) = -1

Next, let's evaluate (-2)^2: (-2)^2 = (-2) * (-2) = 4

Now, we have:

-1 + 4

Finally, add -1 and 4:

-1 + 4 = 3

So, the final result of the expression is 3.
