Answer #1 
1)  sub $10, $8, $6
=>  SPECIAL    rs rt rd 0  SUB
=>  SPECIAL    $8 $6 $10    0  SUB
=>  000000 01000  00110  01010  00000  100010
let's convert 00000001000001100101000000100010 to hexadecimal
Converting 00000001000001100101000000100010 to hexadecimal
0000 => 0
0001 => 1
0000 => 0
0110 => 6
0101 => 5
0000 => 0
0010 => 2
0010 => 2
So, in hexadecimal 00000001000001100101000000100010 is 0x01065022
Answer: 0x01065022

2)  slt $1, $9, $2
=>  SPECIAL    rs rt rd 0  SLT
=>  SPECIAL    $9 $2 $1 0  SLT
=>  000000 01001  00010  00001  00000  101010
Converting 00000001001000100000100000101010 to hexadecimal
0000 => 0
0001 => 1
0010 => 2
0010 => 2
0000 => 0
1000 => 8
0010 => 2
1010 => A
So, in hexadecimal 00000001001000100000100000101010 is 0x0122082A
Answer: 0x0122082A
