Answer 1

So we can go back to old school maths

BODMAS

Now B is bracket so we solve it first

Now in the first inner bracket, you have

3 ** 2 = 9

Then we replace the result so
print((9) // 2)

Now we can go ahead with the division

Mind you / is for float output and // is for int output

So 9 divided by 2 gives 4.5 but since we expect int output you get

4
