144 and 5 x 43 and 5

- math -
**Reiny**, Sunday, May 22, 2011 at 10:27amYou could change to base 10 and then convert your answer.

144_{5}= 1(5^2) + 4(5) + 4 = 49

43 = 4(5)+3 = 23

49x23 = 1127

1127 = 1(625) + 4(125) + 0(25) + 0(5) + 2

= 14002_{5}

or

create a multiplication table in base 5

x 1 2 3 4

1 1 2 3 4

2 2 8 11 13

3 3 11 14 22

4 4 13 22 31

so

144

x43

---------

1042

1242

------

14002
