1. Answer :

36

To find the digital root, add the digits in 36.

= 3 + 6

= 9

Sum of the digits in 36 is a single digit value 9.

So, the digital root of 36 is '9'.

2. Answer :

10

To find the digital root, add the digits in 10.

= 1 + 0

= 1

Sum of the digits in 10 is a single digit value 1.

So, the digital root of 10 is '1'.

3. Answer :

438

To find the digital root, add the digits in 438.

= 4 + 3 + 8

= 15

Here, the sum of the digits in 438 is '15' which is more than 9.

So, add the digits in the sum 15.

= 1 + 5

= 6

Therefore, the digital root of 438 is '6'.

4. Answer :

7999992

Ignoring all 9's in 7999992, we are left with 7 and 2.

= 7 + 2 

= 9

Therefore, the digital root of 7999992 is '9'.

5. Answer :

7826345

Find the digits in 7826345 which add up to 9.

7826345

Ignoring the digits which add up to 9, we are left with 8.

'8' is a single digit value.

Therefore, the digital root of 7826345 is '8'.

6. Answer :

907236

Find the digits in 907236 which add up to 9.

907236

Ignoring the digit 9 and the digits which add up to 9, we are left with the digit zero.

Therefore, the digital root of 907236 is '9'.

7. Answer :

72554

Find the digits in 72554 which add up to 9.

72554

Ignoring the digits which add up to 9, we are left with the digit 5 (≠ 0).

Therefore, the digital root of 72554 is '5'.

8. Answer :

613481

Find the digits in 613481 which add up to 9.

613481

Ignoring the digits which add up to 9, we are left with the digits 1 and 4.

= 1 + 4

= 5

Therefore, the digital root of 613481 is '5'.
