Question

amistre64 · Answer

can you write out the 6th row of the triangle?  those will be needed

amistre64 · Answer

to keep things in order i just stack it all up in this manner and multiply down the columns

..................6th row numbers .............
 x^6  x^5  x^4   x^3   x^2   x^1   x^0
3^0   3^1  3^2  3^3   3^4   3^5   3^6

amistre64 · Answer

so whats the confusion?  the stacking?  the multiplying? or the looking up the numbers from the 6th row?

on wikipedia theres a little animation that will show you the pattern to pascals triangle. your coefficients will be 1,6,15,20,15,6,1. so your answer should be (from what i remember) 1x^6+6x^5(3)+15x^4(3^2)+20x^3(3^3).... x power will decrease, 3 power will increase
