To find: Sum
Answer to Problem 59E
Explanation of Solution
Given information:
Pascal’s Triangle:
Calculation:
Here, we observe that the alternating sum of 1st row gives 0 and sum of 2nd row gives 0 and 3rd row gives 0.
So, it follows the pattern that,
The sum of
The entries of
Therefore, their alternating sum is:
The expansion of expression
According to the Binomial theorem, expansion of
Where
Therefore, the expansion of
Hence proved.
