Question

If x=12 and y=3, what is the value of x−y^2?618381

Answer 1

Step 1. The expression that we have is:

`x-y^2`

And we are given the following values for x and y:

`\begin{gathered} x=12 \\ y=3 \end{gathered}`

Step 2. To find the value of the expression, we need to substitute the values of x and y:

`x-y^2=12-3^2`

Step 3. Before making the subtraction we solve the exponent. 3^2 is equal to 9:

`12-9`

Finally, the result of the subtraction is:

`12-9=\boxed{3}`

Answer:

3
