Solve Binomial Series: Quickly Answer Before Spring Break!

[kollo3]

Can Someone Plz Answer Asap!

My teacher gave me homework and i got to convert for ex. (a+b)squared=a squared+ab+b squared, i got to do this up until to the 15th power. Please anyone have an ez way to do this or a shortcut. PLZ REPLY MY SPRING BREAK IS ALMOST OVER I HAVE LIKE 3 DAYS TO DO THIS

What is your question? You need to expand

(a+b)^2

?

Just write it as

(a+b)(a+b)

and use the properties of multiplication...

(a+b)^{2}=a^{2}+2ab+b^{2} !

Now,are u interested in that

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

,or in that

(a+b)^{15}

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.
