Answer 1

1
     1 1
    1 2 1
   1 3 3 1
  1 4 6 4 1
1 5 10 10 5 1

Question 2

What are the Formulas for Binomial Expansion?

Answer 2

(a+b)^0=1.
(a+b)^1=a+b.
(a+b)^2=(a^2)+2ab+b^2.
(a+b)^3=(a^3)+(3a^2)b+3a(b^2)+b^3.
(a+b)^4=(a^4)+(4a^3)b+(6a^2)b^2+4a(b^3)+b^4.
(a+b)^5=(a^5)+(5a^4)b+(10a^3)b^2+(10a^2)(b^3)+b^5.

Question 3
