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?

What do you mean? explain what you mean by changing bases?

"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]
