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!
