seven girls = 7x2 = 14 legs each girl has 2 legs
each girl has seven backpacks. there are 7 girls . so there are 49 back packs. each back pack has 7 cats .
so there are 49x7 = 343 fat cats
there are 343fat cats. a cat has 4 legs
343 x4 = 1372 legs
each fat cat has 7 little cats. there are 343 fat cats . so there are
343x 7 = 2401 little cats
each little cat has 4 legs
so altogether little cats have 2401 x 4 = 9604legs
total legs = total legs of girls + total legs of fat cats + total legs of little cats
14+1372+9604 = 10990 legs

7 x 2 + 7 x 7 x 7 x 4 + 7 x 7 x 7 x 7 x 4
= 14 + 1372 + 9604
= 1386 + 9604
= 10990 legs
= 14 + 1372 + 9604
= 1386 + 9604
= 10990 legs

Total girls = 7
Backpacks with each girl = 7
Therefore, total backpacks with 7 girls = 7*7
= 49
Each backpack has 7 fat cats
Therefore, total number of fat cats in 49 backpacks = 49*7
= 343
Each fat cat has 7 little cats
Therefore, total number of little cats with 343 fat cats = 2401
Total number of cats ie fat cats and little cats = 2401 + 343
= 2744
Total number of legs = 7*2 + 2744*4
= 14 + 10976
= 10990
Backpacks with each girl = 7
Therefore, total backpacks with 7 girls = 7*7
= 49
Each backpack has 7 fat cats
Therefore, total number of fat cats in 49 backpacks = 49*7
= 343
Each fat cat has 7 little cats
Therefore, total number of little cats with 343 fat cats = 2401
Total number of cats ie fat cats and little cats = 2401 + 343
= 2744
Total number of legs = 7*2 + 2744*4
= 14 + 10976
= 10990

there are 14 girls' legs (7*2)
+ 1372 fat cats' leg (7*7*7*4)
+ 9604 little cats' leg (7*7*7*7*4)
= 10990 leggs
+ 1372 fat cats' leg (7*7*7*4)
+ 9604 little cats' leg (7*7*7*7*4)
= 10990 leggs
