Question: 1 / 400

From the set of numbers 345678234453, how many unique digits are there?

7

8

9

To determine the number of unique digits in the set of numbers 345678234453, we need to identify each distinct digit that appears within that series. The digits present in the number sequence are:

- 3

- 4

- 5

- 6

- 7

- 8

- 2

Checking this sequence, we find that the digits 3, 4, 5, 6, 7, 8, and 2 are all distinct. However, it should be noted that the digits 0 and 1 do not appear at all in this sequence. Thus, counting the unique digits yields a total of 7 different values: 2, 3, 4, 5, 6, 7, and 8.

Considering the choices provided, the correct count of unique digits is determined to be 7. This indicates that the answer should reflect that unique quantity, and therefore, the appropriate answer aligns with that integer value rather than asserting a total that includes digits not present in the original sequence.
