Question

2. Verify | x × y|
= | x | × | y | for
(a) x = 0 and y = -5/11
(b) x = 1/2 and y = -5/6
​

Answer 1

a) | 0×-5/11|=|0|×|-5/11|

|0|=0×5/11

0=0

LHS=RHS

hence proved

b)|1/2×-5/6|=|1/2|×|-5/6|

|-5/12|=1/2×5/6

5/12=5/12

LHS=RHS

Hence proved

In both cases

|X×Y|=|X|×|Y|

Answer 2

Answer:

(0 × -5/11)= 0 ×(1/2 ×-5/6)

0 = 0

Hence verified

lhs = rhs
