Tolong sekali besok mau dikumpulin tolong dijawab ya.....??

1 . 24= 2 x 2 x 2 x 3= 2³ x 3
     40 = 2 x 2 x 2 x 5 = 2³ x 5
     KPK= 2³ x 3 x 5= 8 x 3 x 5 = 120
2. 54= 2 x 3 x 3 x 3= 2 x 3³
    70 = 2 x 5 x 7 = 2 x 5 x 7
    KPK =2 x 3² x 5 x 7
            =2 x 9 x 5 x 7 = 630
3.11³= 1331
   10³= 1000
   2³= 8
1331-1000:8= 1331 - 125=1206 atau 11³-10³:2= 11³-5³=1331-125= 1026
4. 9³= 729
   2³ = 8
    4³= 64
729-8×64=729-512=217 atau 9³-2³x4³= 9³-8³= 729-512=217
5. 10³= 1000
    5³= 125
    8³= 512
1000:125+512= 8+512= 520 atau 10³:5³+8³=2³+8³= 8+512=520
6. 20³= 8000
    4³= 64 
    5³= 125
8000:64+125=125-125= 0 atau 20³:4³-5³= 5³-5³= 125-125= 0
