Prove the divisibility of the following problems: (This is for RSM) 5^31-5^29 is divisible by 100

12^13-12^12-12^11 is divisible by 7 and 19

11^9-11^8+11^7 is divisible by 3 and 37

Will mark brainliest!

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
