Does anyone know what has integers as it's square root?
Snezhnost [94]
It shouldn't be too tough to find one of those, seeing that there are
an infinite number of them.

To create one, take any integer, positive or negative, and multiply it by itself.

Here are a few to put you in the mood:

1,  4,  9,  16,  25,  36,  49,  64,  81,  100,  121,  144,  169,  196,  225,  256,  ...

784,  841,  900,  1024,  1225,  1600,  2500,  3600,  4900,  10000,  1 million,  ...

In 12 years, Janice will be 8 times as old as she was 2 years ago. How old is Janice<br> now?
Setler [38]

Janice is currently 4.

In 12 years, Janice will be 16, and 2 years ago she was 2. That being said, 16 is eight times more than 2, thus meaning she is currently 4 years old.

I hope this helps!
