Question

if a= -1/2 and b = -1/4 verify the following : a×b =b×a​

Answer 1

a × b = b × a

-1/2 × -1/4 = -1/4 × -1/2

1/8 = 1/8

hence a × b = b × a

Answer 2

Answer:

Given :-

• a = $\frac{-1}{2}$
• b = $\frac{-1}{4}$

Step-by-step explanation:

➵ a × b = b × a

➵ $\frac{-1}{2} \: × \: \frac{-1}{4}$ = $\frac{-1}{4} \: × \: \frac{-1}{2}$

➵ $\frac{ -1 \: × \: -1 }{ 2 \: × \: 4 }$ = $\frac{ -1 \: × \: -1 }{ 4 \: × \: 2 }$

➵ $\frac{ 1 }{ 8 }$ = $\frac{ 1 }{ 8 }$

:. a × b = b × a

NOTE :-

• Here the numerators are same so we can multiply directly the numerators and multiply directly the denominators.
