Question

15×[3×(-12)]=(15×3) × -12​

Answer 1

Step-by-step explanation:

15×[3×(-12)]=(15×3)× -12

15×(-36)=45× -12

-540= -540

LHS=RHS

Answer 2

Answer:

To prove : 15×[3×(-12)] = (15×3) × -12

Solution :

LHS = 15 × [ 3×(-12) ]

= 15 × [ -36 ]

= -540

RHS = (15×3) × -12

= (45) × (-12)

= -540

LHS = RHS

hence proved
