Answer:
answer is 39
Step-by-step 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
