What squares consist of three digits 1, 4, and 9? Let’s have the first 9 or so…

The first square in the sequence is 107^2 = 11449.

If you want – have a bash at squares consisting of the three digits 2,4 and 8.

For 2, 4 and 8:
168^2 = 28,224
478^2 = 228,484

2. 2. Kel9902 Said：

For 1, 4, 9: 212^2=44944

3. 3. Kel9902 Said：

For 2, 4, 8: 2878^2 = 8282884

4. 4. Karl Sharman Said：

Sorry Kel9902 – can’t accept 212^2 = 44944 – I need all three digits in the answer, otherwise I would accept 7^2 – and that’s just too easy.
Is anyone trying a logarithmic approach?

Do you mean like this…
107 Squared= 11449
31488 Squared= 991494144
70107 Squared= 4914991449
387288 Squared= 149991994944

How high? 9? This is only 4
