square root of 2025 is 45
you can find this by factorization
2025=3×675
=3×3×225
=3×3×3×75
=3×3×3×3×25
=3×3×3×3×5×5
now square root
3×3×5
=45
If you see 25 as last two digits the other digits are product of two consecutive numbers
means here 20 is product of 4&5
In square root the small number and 5 written in square root
