# Expand Using Pascal’s Triangle (p+1/p)^5 Pascal’s Triangle can be displayed as such:
The triangle can be used to calculate the coefficients of the expansion of by taking the exponent and adding . The coefficients will correspond with line of the triangle. For , so the coefficients of the expansion will correspond with line .
The expansion follows the rule . The values of the coefficients, from the triangle, are .
