Question

If x and y are the number of possibilities that A can assume such that the unit digit of A and Acube ( A ka cube) are same and the unit digit of A ka square and A ka cube are same respectively then the value of x-y is ( where A is a single digit number)

Answer 1

hey bro

these are the possibilities

for a single digit number A

it's cube = to number itself

if A ={1,-1,0}

it's square =number itself

if A={1,0}

x-y=3-2=1

Answer 2

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

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
