Answer:

I just finished taking this test and I just wanted to confirm for all you humans out there, that FencingParry4 is correct! (yay! wooo! celebra-ate!) the answer is indeed 7√3  and  9√3 Great job fencing!

Answer 2

The pair of radicals that is a like pair is  $7\sqrt{3}$ and $9 \sqrt{3}$

Option C is correct

For two radicals to be similar, they must contain the same number in the root operator.

Two like radicals are in the form:

$a\sqrt{b}$ and $c \sqrt{b}$

Since $a\sqrt{b}$ and $c \sqrt{b}$ are like terms, arithmetic operations such as addition, subtraction, multiplication, and division can be carried out on them

Considering the options given, only $7\sqrt{3}$ and $9 \sqrt{3}$ are in the form $a\sqrt{b}$ and $c \sqrt{b}$ because they have equal value inside the root operator.

Therefore, the pair of radicals that is a like pair is  $7\sqrt{3}$ and $9 \sqrt{3}$
