No.
The two digits that equal 150 are 1 and 5, when combined as the two-digit number 15 multiplied by 10. However, if you're looking for two separate digits that sum to 150, that is not possible since the maximum sum of two single digits (9 + 9) is 18. Therefore, there are no two digits that can equal 150 in a traditional sense.
