Expand Using Pascal's Triangle (x+3)^8
Step 1
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 .
Step 2
The expansion follows the rule . The values of the coefficients, from the triangle, are .
Step 3
Substitute the actual values of and into the expression.
