What is your question? You need to expand

[tex](a+b)^2[/tex]

?

Just write it as

[tex](a+b)(a+b)[/tex]

and use the properties of multiplication...

[tex] (a+b)^{2}=a^{2}+2ab+b^{2} [/tex] !!

Now,are u interested in that

[tex] \left[(a+b)^{2}\right]^{15}=(a+b)^{30} [/tex]

,or in that

[tex] (a+b)^{15} [/tex]

Do you know something about the Newton's binomial formula ...?

kollo3:
You know of Newton's binomial formula.
Your teacher is testing you whether you understand how to apply that formula or not.
