I have one problems, it's a number problem where you have to find the mystery number. I'm stuck, and have done some work, but don't know how to continue. Could someone please explain to me how to complete this problem (and what a placeholder is?)
a. I am a four-digit number.
b. I am a multiple of 25.
c. I have an odd number of factors.
d. None of my digits are the same.
e. None of my digits is a square number
I got that the number ends in 25 and the other two digits have to be some form of 3,6,7 or 8. ( In pairs)
PLEASE HELP!!!!!!!!!!
And thanks in advance for the help.
