This is my daughter homework but I don't know how to do it , anyone can help? Q1 : Bill Jones was not anybody famous in the 1970s and 1980s. In what year was he born? Two digits in the year are the same. The sum of the digits is a prime and the product of the square of 18?

okay I just figured out #2, but idk why it wont let me post it on that question, so this is the answer for the second one you posted:
The son is 29 and the dad is 89
7=8x3=24-1=23
11=12x3=36-1=35
13 =13x3=39-1=38
17 =18x3=54-1=53
19 =20x3=60-1=59
23 =24x3=72-1=71
29 =30x3=90-1=89
31 =32x3=66-1=65

Your welcome, and i think this one is 1949 because the square of 18 is 324 and thats what 1x9x4x9 comes out too, plus the 9s are the same and they add up to 23 which is prime :)

"the product of the square of 18"
That is meaningless. A prime number is by definition not the product of anything. That is probably why you can't figure it out.
