The product of the following by suitable rearrangement are:

(a) 2 \times 1768 \times 50

\\ = 2 \times 50\times 1768 \\ = (2 \times 50)\times 1768 \\ = 100\times 1768 \\ = 176800

 

(b) 4 \times 166 \times 25

\\ = 4\times 25 \times 166 \\ = (4\times 25 )\times 166 \\ = 100 \times 166 \\ = 16600

(c) 8 \times 291 \times125

\\ = 8 \times125 \times 291 \\ =( 8 \times125) \times 291 \\ = 1000\times 291 \\ = 291000       

      

(d) 625 \times 279 \times 16

\\ = 625 \times 16\times 279 \\ = (625 \times 16)\times 279 \\ = 10000\times 279 \\ = 2790000

 

(e) 285 \times 5 \times 60

\\ = 285 \times (5 \times 60) \\ = 285 \times 300 \\ = 85500                 

 

(f) 125 \times 40 \times 8 \times 25

\\ = 125\times 8 \times 40 \times 25 \\ = (125\times 8 )\times (40 \times 25) \\ = 1000 \times 1000 \\ = 1000000
