4x10^-3 is another way to represent 3^-5
the 3 in 350 represents 3 hundred's ( 3 100's ) while the 3 in 403 represents 3 units ( 3 1's )
a is the best way to find it if there is points involved so keep that in mind
Answer:1
Step-by-step explanation:

Answer: G) -2</h3>
=======================================================
Explanation:
I'm assuming you meant to say (a+y)^2 + 2y
Replace each copy of 'a' with 5. Replace each copy of 'y' with -3. Use PEMDAS to simplify.
(a+y)^2 + 2y
(5 + (-3))^2 + 2(-3)
(5-3)^2 + 2(-3)
(2)^2 + 2(-3)
4 + 2(-3)
4 - 6
-2
So (a+y)^2 + 2y = -2 when a = 5 and y = -3.
