Answer:

Check the exlanation

Explanation:

1) add $s0,$s0,$s1 \rightarrow R-format

   

opcode                 rs        rt      rd          shamt      function

000000            $s0       $s1    $s0        00000    100000

000000            10000  10001  10000    00000  100000

  = 0X42118020

2) lw $s0,0X20($t7)\rightarrow I-format

opcode                     rs      rt            offset

100000                  $s0     $t7          0X20

100000               10000    01111       0000000000010000

  = 0X820F0010

3) addi $s0,$s0,-10 \rightarrow I-format

opcode             rs           rt            offset

001000            $s0         $s0       -10

001000             10000   10000    1111111111110110

= 0X2210FFF6

4) ori $s1,$a0,100 \rightarrow I-format

opcode             rs        rt            offset

001101             $s0     $a0         100

001101            10000  00100    0000000001100100

= 0X36040064

5) j 0X400C \rightarrow J-format

opcode  rs

000010  0X400C

000010  0000000000100000000001100

= 0X0800400C

aivan3 [116]

Answer:

def first_a(n):

   lst1 =[x for x in range(1,n+1)if x%6==0 or x%11 ==0]

   print(lst1)

Explanation:

Above is a function in python programming language. We have used list comprehension to check numbers that are multiples of 6 or 11 in a range.

When this function is called it will receive an argument (n) of type integer, a range will then be generated from 1 to n+1 since n is inclusive. The modulo operator is used to determine is a value is a multiple of 6 or 11, since their multiples will evaluate to 0
