Answers to #221, #222, #224, #225, #226, #229, and #230:-

Other than #225, #229, and #230, All the answers are correct!

Well done, lightning!

Regarding #227, Evaluate means 'to find the value'. In the question, you are asked to find the total 1+4+9=....1600. As it can be seen, these numbers are squares of 1,2,3, ...40. The formula for sum of squares of the first n natural numbers is given by

In this case, n=40 since √(1600) = 40.

Hence the sum would be (40 x 41 x 81)/6 = 20 x 41 x27 = 820 x 27 = 22140
