Question

Evaluate − 5 x 2 + 4 y 3 when x = − 2 and y = 2

Answer 1

answer is 39

Explanation:

So, we start with the original problem:

3

x

2

−

4

y

2

Then we substitute the given

x

and

y

values into the expression:

3

(

5

)

2

−

4

(

3

)

2

Now, according to the order of operations, we simplify the exponential powers first, thus, reducing the expression to this:

3

(

25

)

−

4

(

9

)

Then, we use the order of operations again and do the multiplication next:

75

−

36

We then use the order of operations a final time and finish off the expression with subtraction:

39
