Is it possible for two bosons to occupy the same quantum state explain?

[somebody-nobody]

Show that the symmetric combination of two single particle wavefunction

Gab(r1,r2)=Ga(r1)Gb(r2)+Ga(r2)Gb(r1)

where G is psi ( i don't have symbol on my computer)

displays the exchange symmetry characteristics of bosons (equation

G(r1,r2)=G(r2,r1))

Is it possible for two bosons to occupy the same quantum state explain?

Please give me some tips how to do first part of the problem. I am totaly lost

Just write r2 where you had r1 and also write r1 where you had r2.
You get the same result.

Let's use 2 simple examples:

5 * 6 = 30. Ok but 6*5 also = 30.
So when you are multiplying 2 things together, it doesn't matter what order you write them in. You get the same result.

Also:
4 + 3 = 7. But 3 + 4 also = 7.
Similar to multiplication. It doesn't matter what order you write the numbers in. You get the same result.

You can also interchange particles among coordinates. You should get the same result.
