Question 954831: Amy knew that her grandmother is no more than 80 years old but wanted to know her correct age. She asked her grandmother the year of her birth. The mathematician grandmother replied that in the year x^2 I was x years old. Can you help Amy find out her grandmother's year of birth and her age at the time of conversation?

The year +x%5E2+ has to make sense
+43%5E2+=+1849+ too long ago
+45%5E2+=+2025+ in the future
+44%5E2+=+1936+ makes sense
If her grandmother was +44+ in +1936,
she was born in the year +1936+-+44+=+1892+
----------------
If she was +80+ during conversation,
+1892+%2B+80+=+1972+
