Question

Find the ones digit of a cube of the number P if the square of P is the 4-digit number xy36.? ​

Answer 1

Answer:

the answer is 6

Step-by-step explanation:

if the square of P ends with 36, then evidently, P ends with 6, because 6x6 =36. no other number's square ends with 36.

so when you cube a number ending with 6, then the unit digit of the cube will be 6, because 6x6x6 = _ _ 6
