Answer:
Suppose we have 2 summations which we wish to multiply. Summation 1: the sum of all odd numbers 1 + 3 + 5 + ... + (2k-1) = k*k Summation 2: the sum of all even numbers 2 + 4 + 6 + ... + 2k = k * (k + 1) We could multiply each term on the left side of the equal sign, one by one and make a sum: 1*2 + 3*4 + 5*6 + ... + (2k - 1) * 2k OR We could mutiply the right sides of the equal sign (K*K) * K * (k + 1) = __________simplify.
