Please help with solving this questions for my son, thanks.

I am just gonna help you.

Example 1.
for the above part of example 1

Square root of 9 = 3

Square root of 49 = 7

7-3 = 4

7+4= 13

Square of 13 that is 13 x 13 = 169

For the below part of example 1

Square root of 25 = 5

Square root of 81 = 9

9-5 = 4

9+4 = 13

Square of 13, that is 13x13 = 169.

Example 2.
For the above part

Square root of 4 = 2

Square root of 36 = 6

6-2 = 4

6+4 = 10

Square of 10, that is 10x10 = 100

For the below part

Square root of 16 = 4

Square root of 64 = 8

8-4= 4

8+4 = 12

Square of 12, which is 12x12 = 144.

question 1.

for the bottom/ below part:

Square root of 9 = 3

Square root of 25 = 5

5 - 3 = 2

5 + 2 = 7

Square of 7, which is 7 x 7 = 49

Ans = 49


Question 2.

For the above part

Square root of 1 = 1

Square root of 25 = 5

5 - 1 = 4

5 + 4 = 9

Square of 9, which is 9 x 9 = 81

Ans = 81


Question 3.

For the bottom or below part

Square root of 36 = 6

Square root of 64 = 8

8 - 6 = 2

8 + 2 = 10

Square of 10 which is 10 x 10 = 100

Ans = 100

question 4.

You didn't snap question number 4.

Question 5.

For the above part

Square root of 169 = 13

Square root of 121 = 11

It is in descending order, so we use the minimum value which is 11 and subtract it form the difference between 13 and 11
13 - 11 = 2

11 - 2 = 9

Square of 9, which is 9 x 9 = 81

Ans = 81

Question 6.

For the above part

Square root of 144 = 12

Square root of 64 = 8

It is in descending order so we make use of the minimum value which is 8 and subtract it from the difference between 12 and 8
12 - 8 = 4

8- 4 = 4

Square of 4, which is 4 x 4 = 16

Ans = 16

question 7

not clear.



The Normal way of solving these questions for the level of your son shouldn't be the solution I gave.

I shall give you the shorter and simpler solutions

Thanks, expecting.
