The pair of radicals that is a like pair is [tex]7\sqrt{3}[/tex] and [tex]9 \sqrt{3}[/tex]
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:
[tex]a\sqrt{b}[/tex] and [tex]c \sqrt{b}[/tex]
Since [tex]a\sqrt{b}[/tex] and [tex]c \sqrt{b}[/tex] are like terms, arithmetic operations such as addition, subtraction, multiplication, and division can be carried out on them
Considering the options given, only [tex]7\sqrt{3}[/tex] and [tex]9 \sqrt{3}[/tex] are in the form [tex]a\sqrt{b}[/tex] and [tex]c \sqrt{b}[/tex] because they have equal value inside the root operator.
Therefore, the pair of radicals that is a like pair is [tex]7\sqrt{3}[/tex] and [tex]9 \sqrt{3}[/tex]
