I guess, you mean square root
2sqrt%28+45%29-3sqrt%285%29-4sqrt%28125%29
= 2sqrt%28+3%5E2%2A5%29-3sqrt%285%29-4sqrt%285%2A5%5E2%29
= 3%2A2sqrt%28+5%29-3sqrt%285%29-5%2A4sqrt%285%29
= 6sqrt%28+5%29-3sqrt%285%29-20sqrt%285%29
=+6sqrt%28+5%29-23sqrt%285%29
=+-17sqrt%285%29
or, as decimal:
=+-17%2A2.23606797749979=38.013...rounded to 38
