Answer:
Step-by-step explanation:
Let us consider the given number as two groups starting from the unit digit.
Here the groups are: 648 which is the first group and 10 which is the second group.
From the first group we calculate the unit digit.
The unit digit of 648 is 8=2³. Therefore the unit digit of our required number is 2.
Now considering the second group for the 10's digit,
8>10>27
i.e., 2³>10>3³.
Here we choose the smaller number that is 2 as our 10's digit.
∴, ∛10648=22
