Convert 333012₄ into Base 10.
  
Solution:
                             
The given number which is 333012₄ is written in Base 4. Base 4 number is also called quaternary system. The digits of Base 4 number are 0, 1, 2, and 3.
   
On the other hand, Base 10 number is a number whose digits are 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. If you don't see any subscript at the given number, then that number is written in Base 10. Base 10 number is also called decimal system. Base 10 number is a common number that we are using right now in everyday life. 
       
Now, let's convert 333012₄ into Base 10. How? Let's multiply each digits by the powers of 4 as follows:
         
Base 4 Digits:        3      3      3      0      1      2          
Multiply by:            4⁵     4⁴     4³    4²     4¹     4⁰    
             
Add all the digits, we have
                 
(3 x 4⁵) + (3 x 4⁴) + (3 x 4³) + (0 x 4²) + (1 x 4¹) + (2 x 4⁰) = 3072 + 768 + 192 + 0 + 4 + 2 = 4038
             
Therefore, 333012₄ = 4038

Convert 213₄ into Base 10.
  
Solution:
                             
The given number which is 213₄ is written in Base 4. Base 4 number is also called quaternary system. The digits of Base 4 number are 0, 1, 2, and 3.
   
On the other hand, Base 10 number is a number whose digits are 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. If you don't see any subscript at the given number, then that number is written in Base 10. Base 10 number is also called decimal system. Base 10 number is a common number that we are using right now in everyday life. 
       
Now, let's convert 213₄ into Base 10. How? Let's multiply each digits by the powers of 4 as follows:
         
Base 4 Digits:        2      1      3          
Multiply by:            4²     4¹     4⁰    
             
Add all the digits, we have
                 
(2 x 4²) + (1 x 4¹) + (3 x 4⁰) = 32 + 4 + 3 = 39
             
Therefore, 213₄ = 39

Convert 568702 into Base 4.
  
Solution:
                                      
The given number which is 568702 is written in Base 10. 568702 can also be written as 568702₁₀. If you don't see any subscript at the given number, then that number is written in Base 10. Base 10 number is also called decimal system.  The digits of Base 10 number are 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. Base 10 number is a common number that we are using right now in everyday life. 
   
On the other hand, Base 4 number is a number whose digits are 0, 1, 2, and 3. If you see a subscript of 4 at the given number, then that number is written in Base 4. Base 4 number is also called quaternary system. 
      
Now, let's convert 568702 into Base 4. How? Let's divide 568702 by 4 as follows:
   
                568702 ÷ 4 = 142175 + R(2)
   
Next, let's divide the quotient, which is 142175, as follows: 
    
                568702 ÷ 4 = 142175 + R(2)
                142175 ÷ 4 =   35543 + R(3)
 
Do the same thing with 35543 until the quotient is 0 as follows:
   
                568702 ÷ 4 = 142175 + R(2)
                142175 ÷ 4 =   35543 + R(3)
                  35543 ÷ 4 =     8885 + R(3)
                    8885 ÷ 4 =     2221 + R(1) 
                    2221 ÷ 4 =       555 + R(1) 
                      555 ÷ 4 =       138 + R(3) 
                      138 ÷ 4 =         34 + R(2) 
                        34 ÷ 4 =           8 + R(2) 
                          8 ÷ 4 =           2 + R(0) 
                          2 ÷ 4 =           0 + R(2) 
                   
The remainders will be the digits of Base 4 number. Use the digits of the remainders from bottom to top. Therefore,
   
                  568702 = 2022311332₄
