Mathematics Worksheet/Algebra/Pascal's Triangle

Study the Pascal's Triangle below.

1                                       1   1                                      1   2   1                                    1   3   3   1                                  1   4   6   4   1                                1   5  10  10   5   1

This table showing the $$(x+y)^n$$, exponential results and coefficients.

Now do the questions carefully using Pascal's triangle; Use  to write exponentiation.  {
