Question

verify (-7) × [(-8) + 9] =[-7 × (-8)] + [(-7) ×9]​

Answer 1

Answer:

L.H.S=

(-7)×[(-8)+9]

(-7)×(+1)

=7

R.H.S=

[-7×(-8)]+[(-7)×9]

(56)+(-63)

56+-63

-7

therefore,L.H.S=R.H.S

Step-by-step explanation:

Hope to you help ful

Answer 2

Answer:

It can be verified using LHS and RHS separately.

Step-by-step explanation:

Taking Left hand side

$(-7)*[(-8)+9]$

Using BODMAS

$(-7)*[1]$

$=-7$

Taking Right Hand Side

$[-7*(-8)]+[(-7)*9]$

Using BODMAS

$[56]+[-63]$

$=56-63$

$=-7$

Since LHS=RHS

It is verified.
