Answer 1

Is the whole thing to the second power or just the 6?

Answer 2

Just the 6.

Answer 3

ok then using PEMDAS, means that multiplication is first, so:

3+20-6.

Complete that expression^. That's the answer to A.

Remember to square 6.

So essentially,

3+20-36 would be the answer to A.

Answer 5
