17(three)

Answer 3

i am confused,
do you want to take the ordinary base ten number seventeen (17) and convert it to base 3?

Answer 4

Yeah

Answer 5

powers of 3 are 1, 3, 9, 27, 81 etc
the largest power that goes in to 17 is 9
so there is a 1 in the "nines" place
then 17 - 9 = 8
there are two 3's in 8, so a 2 goes in the threes place
then 8 - 6 = 2, so also a 2 goes in the ones place
\[17=122_3\]

Answer 6

in other words,
\[17=1\times 3^2+2\times 3^1+2\times 3^0\]

Answer 7

why do you subtract?
