$= > 9 \sqrt{5} - 4 \sqrt{5} + \sqrt{125}$

take a look on √125 it can be further simplify

e.g=>√5×5×5=5√5

so ,put 5√5 in place of √125

$= > 9 \sqrt{5} - 4 \sqrt{5} + 5 \sqrt{5}$

$= > 5 \sqrt{5} + 5 \sqrt{5}$

$= > 10 \sqrt{5}$

$\huge\mathcal{More\: to\: know }$

• Like root terms can be added or Subtracted only
• power of root is 1/2.e.g=>√5=(5)^1/2
• If value inside can be simplified then simplify it and write common factor outside and remaining inside root.e.g=>8 (2×2×2) which can be written as 2√2
