Answer 1

$\red{ The \: value \:of \: 2\sqrt{5} + \sqrt{125}}$

$= 2\sqrt{5} + \sqrt{5\times 5 \times 5}$

$= 2\sqrt{5} + 5\sqrt{5}$

$=( 2+5)\sqrt{5}$

$=7\sqrt{5}$

Therefore.,

$\red{ The \: value \:of \: 2\sqrt{5} + \sqrt{125}}\green { = 7\sqrt{5}}$

Answer 2

Answer:

$7 \sqrt{5} \: is \: the \: \ \: answer \: my \: friend$

$2 \sqrt{5 } + \sqrt{125}$

$\sqrt{125} = \sqrt{5 \times 25} = 5 \sqrt{5}$

so

$2 \sqrt{5 } + 5 \sqrt{5} = 7 \sqrt{5}$

or else you can write it as

$7 \sqrt{5} = \sqrt{5 \times 49} = \sqrt{245}$ok friend I think you got the answer
