Let's have, which ones have decimal results, and which ones don't.
- √2 = 1.41
- √144 = 12²
- √1000 = 31.62
- √49 = 7²
- √324 = 18²
- √6 = 2.449
- √900 = 30²
- √40 = 6.32
Those that will give solutions, with integers or exact numbers are:
Answer ✅: √144, √49, √324, √900
They are the square roots, whose result is exact numbers. That is, it has no decimals.
