Question

if a = 1/2 , b = 3/4 verify a*b = b*a

Answer 1

Step-by-step explanation:

a = 1/2 , b = 3/4

a*b=1/2*3/4=3/8

b*a=3/4*1/2=3/8

hence verified

a*b = b*a

Answer 2

Answer:

$a \times b = b \times a \\ a = \frac{1}{2} \\ b = \frac{3}{4} \\ lhs = a \times b \\ = \frac{1}{2} \times \frac{3}{4} \\ = \frac{3}{8} \\ rhs = b \times a \\ = \frac{3}{4} \times \frac{1}{2} \\ = \frac{3}{8}$
