1. Given in decimal system (base 10),
x = 81.3
find x in binary base approximated to 3 binary places.
Hint: Multiply by the required 2^k, round, convert to binary, and then move the binary point k places to the left!!
2. Given in duo-decimal system (base 12),
x = (80a2)12
Calculate 10x in octal system (base 8)
10 x = .....................
3.
Calculate the expression and give the final answer in the octal system with 2 octal places accuracy:
(x w -y z -3 w2)2
with:
x=(3E0)16
y=(111000)2
z=(8)10
w=(20)8
4.
Given in hexadecimal system (base 16),
x = (92B4)16
Find x2-(1280)10x in octal system (base 8)
x2-1280x = (.............................)8
