Question

If x and y are the no. of possibilities that A can assume such that the unit digit of A and A^3 are same and the unit digit of A^2 and A^3 are respectively , then the value of x-y is (where A is a single digit)

Answer 1

hi,

there is some questions error
if the question is:
if X and y are the no.of possibility that A can assume such that the unit digit of A and A^3 are same and the unit digit of A ^2 and A ^3 are same.then find the value of X - y .where A is a single digit

if it is so
then the answer is 2
and solution is in photo

bye
hope you like it

Answer 2

Thank you for asking this question. Here is your answer:

These are the possibilities  

For a single digit number A  

it's cube  is equal to it's number itself  

if A ={1,-1,0}

it's square is equal to it's number itself

if A={1,0}

x-y=3-2=1
