is the answer.

Step-by-step explanation:

If we put a penny on the first square of a chess board, 2 on second, six on third and we keep on doing double for the next square then it will form a geometric sequence in the form of

1, 2, 4, 8, 16.........n terms

Now we have to calculate the pennies on square 33 that will be

So pennies on 33rd square will be

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be
