    ok... so pascal's triangle will give the coefficients |dw:1358116269604:dw| starting with (3v)^5 and (s)^0 decrease the power or 3v by 1 each time and increase the power of s so you will have, using the last line of pascals triangle.. \[1 \times (3v)^5\times (s)^0 + 5\times (3v)^4\times(s)^1 + 10 \times (3v)^3 \times (s)^2 +...... \] you need to continue until your have (3v)^0 and (s)^5
