Question

9x4(2x3-5x4)×5x6(x4-3x2)​

Answer 1

Step-by-step explanation:

according to DOMAS

i.e division, multiplication, addition, subtraction

we have to follow in sequence rule

i.e first we have to do division after that multiplication after that addition after that subtraction

then

=9(4)(2(3)-5(4))(5)(6)(4-3(2))

=36(6-20)(30)(4-6)

=36(-12)(30)(-2)

=36(-360)(-2)

=36(720)

=25920
