Question 848189: I want to know if I have the right answer to 24 base 5 x 3 base 5. The answer I got is 122 base 5. Found 2 solutions by swincher4391, richwmiller:Answer by swincher4391(1107) (Show Source):
You can put this solution on YOUR website! 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'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
