Question

Verify a x b = b x a for a=-3/5 and b=7/8

Answer 1

Answer:

$a \times b = b \times a$

$\frac{ - 3}{5} \times \frac{7}{8} = \frac{7}{8} \times \frac{ - 3}{5}$

$\frac{ - 21}{40} = \frac{ - 21}{40}$

Since LHS = RHS

Therefore a × b = a × b

Answer 2

Answer:

LHS:

-3/5×7/8

=-21/40

RHS:

7/8×-3/5

=-21/40

LHS=RHS Proved
