Question

0xBED into 3-base representation

Answer 1

0xBED is an hexadecimal representation.
Transforming to decimal first:
B => 11
E => 14
D => 13

`11*16^2+14*16+13=3053`
Now by successive devisions, we get the base three:

`3053=2+2*3^3+3^4+3^6+3^7`
And the resulting base three expression:

`11012002_(3)`
