Question

The digit in the unit’s place of the cube of 47 is: a) 9 b) 7 c) 3 d) 1

Answer 1

Answer:

The correct option is;

c) 3

Step-by-step explanation:

In place value, the digits of a large number are grouped in threes with the values arranged from left to right for example from left to right, e can have;

...billion...million...thousands...ones

For the international system, the place value chart can be written as follows;

Millions ${}$                              Thousands                           Ones

Hundred

HM ${}$    TM ${}$ M           HT      TT       U                        H      T        U

Where;

HM = Hundred million

TM = Ten million

M  = Million

HT = Hundred Thousand

TT  = Ten Thousand

T =Thousand

HT = Hundred

TT  = Ten

T or U =Ones or units

The cube of 47 is given as follows;

47³ = 103823

Therefore, the digit in the unit place of the cube of 47 is given as follows;

Millions ${}$                              Thousands                           Ones

Hundred

HM ${}$    TM ${}$ M           HT      TT       U                        H      T        U

                                  1          0       3                         8       2       3                  

The digit in the unit place of the cube of 47 is 3
