Answer 1

Answer:

answer=165 correctly answer

Answer 2

Given,

The sum for evaluation is 13 + 23 + 33 +43 + 53

To find,

The final answer of the evaluation.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

Here, we just need to add all the numbers with each other.

¹

13

23

33

43

+ 53

_____

165

Firstly, we have added all the five digits at the unit positions of the given five numbers.

= (3+3+3+3+3) = 15

Now, we have written the unit digit of the above mentioned sum, in the final answer (ie. 5). And, the digit at the tenth position of the above mentioned sum (ie. 1) will be added with the digits at the tenth positions of the given five numbers (ie. 1,2,3,4,5)

= (1+1+2+3+4+5) = 16

And this 16 will be kept on the left side of the already existing part of the final answer (ie. 5)

So, the final answer = 165

Hence, the final answer is 165
