​
​

Answer 1

Answer:

yes you are correct..........

Answer 2

Answer:

unlike surds  => not like surds

Step-by-step explanation:

$9\sqrt{12}$  = $9*\sqrt{4*3}$  =  $9*2\sqrt{3}$  = $18\sqrt{3}$

$6\sqrt{2}$                                          = $6\sqrt{2}$

in the first case, the radicand is 3, whereas in the next one, the radicand is 2.

hence the 2 surds are unlike surds.
