Answer 1

Answer:

Step-by-step explanation:

a)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

b)15625=25×25×25

c)110592=48×48×48

d)91125=45×45×45
