Question

write the squares of first ten natural numbers​

Answer 1

Step-by-step explanation:

The square of the first 10 natural numbers namely 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10. Their squares will be 1, 4, 9, 16, 25, 36, 49, 64, 81 and 100. Using the formula of mean, we get 1+4+9+16+25+36+49+64+81+10010=38510

Answer 2

Answer:

1, 4, 9, 16, 25, 36, 49, 64, 81 and 100

Step-by-step explanation:

1 * 1 = 1

2 * 2 = 4

3 * 3 = 9

4 * 4 = 16

5 * 5 = 25

6 * 6 = 36

7 * 7 = 49

8 * 8 = 64

9 * 9 = 81

10 * 10 = 100

Means:

⇒  Mean = 10(11)(21)610 = 10 (11) (21) 6 (10) = 11 (21) 6

⇒ 2316

⇒ 38.5

NOTE:

In this question, you may get confused while starting the solution with the formula of sum of first n natural numbers. You can also solve this question by directly calculating the mean of the square of the first 10 natural numbers namely 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10. Their squares will be 1, 4, 9, 16, 25, 36, 49, 64, 81 and 100. Using the formula of mean, we get

1 + 4 + 9 + 16 + 25 + 36 + 49 + 64 + 81 + 100 / 10 = 38510

⇒ 38

Hence, the answer is verified as well.
