plz helppppppppppo its urgent​

Answer 1

Answer:

1) DIVISIBILITY RULE OF 2 :

if the unit digit of the given number is 2 or 0 or multiples of 2 then the given number is divisible by 2 .

DIVISIBILITY RULE OF 3 :

if the sum of the digits of the given number is divisible by 3 then the given number is divisible

by 3 .

DIVISIBILITY RULE OF 4 :

If the last two digits of the given number is divisible by 4 then the number is divisible by 4.

DIVISIBILITY RULE OF 5 :

If the unit digit of the given number is 0 or 5 then it is divisible by 5 .

DIVISIBILITY RULE OF 6 :

If the given number is divisible by 2&3 then the given number is divisible by 6 .

DIVISIBILITY RULE OF 9 :

If the sum of the digits of the given number is divisible by 9 then the given number is divisible

by 9 .

DIVISIBILITY RULE OF 10:

If the last digit of the given number is 0 then the given number is divisible by 10.

DIVISIBILITY RULE OF 11:

If the sum of the digits in even places is equal to the sum of odd places then the given number is divisible by 11.

EXAMPLE : 9317

see the underlined digits places are even places

∴sum of the digits in even places = 3+7 = 1

sum of the digits in odd placesb= 9+1 = 10

Here both sums are equal so 9317 is divisibleby11

2) 6252 = 6×10^3 + 2×10^2 + 52

809176 = 8 × 10^5+ 0×10 + 9×10^3 + 1×10^2 + 7×10 + 6

20176 = 2×10^4 + 0×10 + 1×10^2 +7×10 ++6×10^0

(iam not sure of 2nd answer )

HOPE IT HELPS U !!!!
