1. (567)₈ = (      ?      )₁₆

Solution:
`(567)_8 = (underline{" "})_16`


First convert octal to binary
`(567)_8 = (underline{" "})_2`

5	6	7
101	110	111

`:. (567)_8 = (underline{101110111})_2`


Now convert binary to hexadecimal
`(101110111)_2 = (underline{" "})_16`

0001	0111	0111
1	7	7

`:. (101110111)_2 = (underline{177})_16`


`:. (567)_8 = (underline{177})_16`

2. (4321)₈ = (      ?      )₁₆

Solution:
`(4321)_8 = (underline{" "})_16`


First convert octal to binary
`(4321)_8 = (underline{" "})_2`

4	3	2	1
100	011	010	001

`:. (4321)_8 = (underline{100011010001})_2`


Now convert binary to hexadecimal
`(100011010001)_2 = (underline{" "})_16`

1000	1101	0001
8	D	1

`:. (100011010001)_2 = (underline{8D1})_16`


`:. (4321)_8 = (underline{8D1})_16`
