Find the product by a suitable rearrangement:

(a) \[2\times 1768\times 50\]

(b) \[4\times 166\times 25\]

(c) \[8\times 291\times 125\]

(d) \[625\times 279\times 16\]

(e) \[285\times 5\times 60\]

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

Answer:

(a) \[2\times 1768\times 50=(2\times 50)\times 1768\]

\[=100\times 1768\]

\[=176800\]

(b) \[4\times 166\times 25=(4\times 25)\times 166\]

\[=100\times 166\]

\[=16600\]

(c) \[8\times 291\times 125=(8\times 125)\times 291\]

\[=1000\times 291\]

\[=291000\]

(d) \[625\times 279\times 16=(625\times 16)\times 279\]

\[=10000\times 279\]

\[=2790000\]

(e) \[285\times 5\times 60=285\times (5\times 60)\]

\[=285\times 300\]

\[=85500\]

(f) \[125\times 40\times 8\times 25=(125\times 8)\times (40\times 25)\]

\[=1000\times 1000\]

\[=1000000\]
