To determine the range of Raj's classmates' math scores, we need to follow these steps:

1. Identify all the scores: The scores given are 98, 76, 100, 88, 82, and 70.

2. Find the maximum score: From the list, the highest score is [tex]\(100\)[/tex].

3. Find the minimum score: From the list, the lowest score is [tex]\(70\)[/tex].

4. Calculate the range: The range is found by subtracting the minimum score from the maximum score. Hence,
[tex]\[ \text{Range} = \text{Maximum score} - \text{Minimum score} \][/tex]
So,
[tex]\[ \text{Range} = 100 - 70 = 30 \][/tex]

Therefore, the range of Raj's classmates' test scores is [tex]\(30\)[/tex].

So, the correct answer is [tex]\(30\)[/tex].
