 * Accommodating Squares
 * Can you find two three-digit square numbers (no noughts) that, when put together, will form a six-digit square number?
 * Thus, $324$ and $900$ (the squares of $18$ and $30$) make $324 \, 900$, the square of $570$, only there it happens there are two noughts.
 * There is only one answer.
