who gives right answer with explanation I will mark them as brainlist......​

Answer 1

Answer:

12.726

or

$-9\sqrt{2}$

Step-by-step explanation:

on simplifying the roots we get,

$2\sqrt{2*3*3} +3\sqrt{5*5*2}-5\sqrt{2*3*3*2*2}$

which is,

$6\sqrt{2} +15\sqrt{2} -30\sqrt{2}$

=> $6\sqrt{2}- 15\sqrt{2}$

=> $-9\sqrt{2}$ ------(answer)

can also be written as ,

-9 * 1.414

= 12.726
