Question

Q. Verify the following.

1. {(-7)×(-12)}×8=(-7)×{(-12)×8}

2. 19×{24×(-32)} = (19×24)×(-32)

3. (-12){13+(-45)} = {(-12)×(13)} + {(-12)×(-45)}


please explain it step by step ​

Answer 1

Answer:

1. {(-7)×(-12)}×8=(-7)×{(-12)×8}

=  {84} *8   =   (-7) * {-96}

=  672       =      672

 L.H.S             R.H.S

verify

2. 19×{24×(-32)} = (19×24)×(-32)

=  { 19* ( - 768 )   =    (456) * (-32)

=  14592             =           14592

   L.H.S              =           R.H.S

verify

3. (-12){13+(-45)} = {(-12)×(13)} + {(-12)×(-45)}

=  (-12) { -585 }    =    {156} + { + 540 }

=  7020              =             696

   L.H.S              =             R.H.S

-----------------------------------------------------------

1. {(-7)(-12)}-8 = (-7)×{(-12)×8}

(84) *8 = (-7) * {-96}

= 672 = 672

L.H.S = R.H.S

Verified

------------------------------------------------------------

2. 19×(24×(-32)} = (19×24)×(-32)

(19* (-768) = (456) * (-32)

= 14592 = 14592

L.H.S = R.H.S

Verified

------------------------------------------------------------

3. (-12)[13+(-45)} = {(-12)×(13)} + {(-12)×(-45)}

= (-12) {-585} = (156} + { + 540 }

= 7020 = 696

L.H.S ≠ RHS.

Do not verified.
