Answer:

Firstly consider  

LHS:  

5

−9

​  

×  

3

−10

​  

×  

−4

21

​  

=  

(5×3)

(−9×10)

​  

×  

−4

21

​  

=  

15

90

​  

×  

−4

21

​  

 

(15×−4)

(90×21)

​  

=  

−60

1890

​  

×−1=  

60

−1890

​  

 

Further by dividing  

60

−1890

​  

 by using common divisor 10 we get,  

6

−189

​  

 

Further by dividing  

6

−189

​  

 by using common divisor 3 we get,  

2

−63

​  

 

RHS:  

5

−9

​  

×  

3

−10

​  

×  

−4

21

​  

 

=  

5

−9

​  

×  

3×−4

−10×21

​  

 

=  

5

−9

​  

×  

−12

−210

​  

 

=  

5×−12

−9×210

​  

=  

−60

1890

​  

×−1=  

60

−1890

​  

 

Further by dividing  

60

−1890

​  

 by using common divisor 10 we get,  

6

189

​  

 

Further by dividing  

6

−189

​  

 by using common divisor 3 we get.  

2

−63

​  

 

∴LHS=RHS is verified.
