find 15x(-25)x(-4)x(-10) using suitable properties

Answer :

We have  : 15 $\times$ ( - 25 ) $\times$ ( - 4 ) $\times$  ( - 10 )

Now we use commutative law  and get

=  ( - 25 ) $\times$ ( - 4 ) $\times$  15 $\times$( - 10 )

=  100  $\times$  - 150

=  - 15000                                                                        ( Ans )
