D) is the correct answer because in this description it doesn't say that any of the students dislike a type of ice cream, just that they don't prefer it.
b] 5√ 6 and 6√ 5
c] 7√ 3 and 9√ 3
d] 9√ 2 and -9√ 3
The pair which have the same radicals is the pair of like radicals which are 7√ 3 and 9√ 3 therefore, option (C) will be correct.
The number system is a way to represent or express numbers.
Any of the multiple sets of symbols and the guidelines for utilizing them to represent numbers are included in the Number System.
Given four radicals pair are,
2√ 3 and 2√ 5
5√ 6 and 6√ 5
7√ 3 and 9√ 3
9√ 2 and -9√ 3
The only pair which have the same radical value (√ 3) is 7√ 3 and 9√ 3
Hence "The pair which have the same radicals is the pair of like radicals which are 7√ 3 and 9√ 3".
