Question

2. Prove the following:
() (-20) * (13x4) = [(-20)x13] 4
(n) [(-50)x(-2)]*(-3)=(-50)x[(-2)x(-3)]
(1) [(-4)x(-3)]*(-5)=(-4)x[(-3)x(-5)]​

Answer 1

Answer:

see the explanation

Step-by-step explanation:

1.

LHS

=(-20) × (13×4)

= (-20) × 52

= - 1040

RHS

= [(-20)×13]4

= (-260) × 4

= -1040

hence LHS = RHS (PROVED)
