## Loujoelou 3 years ago Which of the following is the expansion of (x + 5)^6? My answer is x^6 + 5x^5 + 25x^4 + 125x^3 + 625x^2 + 3125x + 15625. Can anyone just check to see if this is right?

1. Migitmack

HOLY CRAP that is long

2. ParthKohli

1,6,15,20,15,6,1 are the coefficients. http://en.wikipedia.org/wiki/Pascal%27s_triangle#Rows

3. Loujoelou

Yes, for the pascal triangle 6th row.

4. ParthKohli

Yeah, so that is correct.

5. Loujoelou

11. Loujoelou

10th or 11th depends if you take geometry first or not.

12. ParthKohli

Not really; learn it whenever you need.

13. Loujoelou

At least for the standard student it would be that.
