Question

What is the third term of (a + b)^11?

Answer 1

use pascal's triangle for this one. go down to the 11th row of the triangle and find the third term

Answer 2

I think I am having trouble setting up pascals triangle for this one. Can you help me? I have a few problems like this

Answer 3

if you see 6C3 , do you know what it mean?

Answer 4

no should I?

Answer 5

1
11
121
1331
14641..... and keep doing this for 11 rows

Answer 6

have to, search google about pascal and something related, because pascal triangle is good if the exponent is low, as 3,4,5, to 11 and up, pascal takes you forever to solve

Answer 7

however, pascal is basic, ok, let dubindabay help you

Answer 8

why do you use numbers if it says (a+b)^11? Another problem I have is (x+2)^5

Answer 9

pascal's triangle tells you the coefficients of each term. so in the general form you have something that looks a little like this: p_1*a^n*b^0+p_2*a^n-1*b^1.....
so the first term of your problem would be:
1*a^11
the second term is:
11*a^10*b

Answer 10

I wish I could understand. Its not clicking.

Answer 11
