7 x 5 x 125 x 2 x 8
= 7 x ( 5 x 2 ) x ( 125 x 8 )
= 7 x 10 x 1000
= 70 x 1000
= 70 000
7 x 5 x 125 x 2 x 8
= 7 x ( 5 x 2 ) x ( 125 x 8 )
= 7 x 10 x 1000
= 70 000
7 x 5 x 125 x 2 x 8
= 7 x ( 5 x 8 ) x ( 125 x 2 )
= 7 x ( 40 x 250 )
= 7 x 10000
= 70000
7 x 5 x 125 x 2 x 8 = 7 x ( 5 x 2 ) x ( 125 x 8 )
= 7 x 10 x 1000
= 70000
