    Why don't you first write 314_5 in base 10 and then transform it to base 8?

    First convert to base 10. Do you know what the 3 represents in 3145?

    "Base" here is more specifically called "radix", but the word base is almost always used in English except in advanced academic texts.

    Maybe I shouldn't do this, but since this is not the homework forum:

    [itex](3*5^2)+(1*5)+4=?[/itex]. Now express the result in base 8. Hint: [itex]100_{8} = 64_{10}=8^2[/itex]
