@Minipanda, in Hexa Decimal we have A=10, but 10 in Hexa Decimal lead to 16 right.

Here the Base is 81, you did not have sufficient A,B,C,.... therefore they directly given that notation

Finally what i want to say **34** means it is **thirty four but not three and four**....

if that is three and four, your representation is correct.

there is no trick its all about concept :

its simple :

for convenience use : (A96)_{16 }<==> ()_{2}

what we do here is plot value of hexadecimal number in terms of binary form. where each value of hex. has 4units . (A96)_{16} = (1010 1001 0110)_{2}

similary when we convert each value of base 81 in base 3, it will be plotted into 4 units. (3^{4} = 81) as its themaximum space we can give to base 3 when we reduce from base 81.

so, (70 34 3 )_{81}= (2121 1021 0001)_{3}
