Find the number that satisfies all of the following conditions:
A twodigit number,
A perfect square,
A power of 3,
The digit product < 10

For a square to be a power of three, the original number itself must be a power of 3, namely 3, 9, 27, etc.
Which of the squares of these numbers satisfies all of the above conditions? 
Is the answer 81?

Correct! Well done!

Thanks,,,

You're welcome! :)
