1. (951)₁₆ = (      ?      )₈

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


First convert hexadecimal to binary
`(951)_16 = (underline{" "})_2`

9	5	1
1001	0101	0001

`:. (951)_16 = (underline{100101010001})_2`


Now convert binary to octal
`(100101010001)_2 = (underline{" "})_8`

100	101	010	001
4	5	2	1

`:. (100101010001)_2 = (underline{4521})_8`


`:. (951)_16 = (underline{4521})_8`

2. (FC3A)₁₆ = (      ?      )₈

Solution:
`(FC3A)_16 = (underline{" "})_8`


First convert hexadecimal to binary
`(FC3A)_16 = (underline{" "})_2`

F	C	3	A
1111	1100	0011	1010

`:. (FC3A)_16 = (underline{1111110000111010})_2`


Now convert binary to octal
`(1111110000111010)_2 = (underline{" "})_8`

001	111	110	000	111	010
1	7	6	0	7	2

`:. (1111110000111010)_2 = (underline{176072})_8`


`:. (FC3A)_16 = (underline{176072})_8`
