<PRE><B>Question 848189</B>
A couple ways we could do this.

Convert to base 10

4 + 2*5 = 14(base 10)
3 = 3(base 10)

14 * 3 = 42

42/5 = 8 r 2
8/5 =  1 r 3
1/3 =  0 r 1

read from bottom to top.

132(base 5)

If you don&#39;t want to convert from base 5 to base 10, make a times table:

Base 5
times table	0	1	2	3	4
---------0	0	 	 	 	 
---------1	0	1	 	 	 
---------2	0	2	4	 	 
---------3	0	3	11	14	 
---------4	0	4	13	22	31

  24
x  3
------
-   22
  11
-------
  132
