Question

\(\left(\frac{1}{57}+\frac{1}{5757}+\frac{1}{23}\right).\left(\frac{1}{2}-\frac{1}{3}-\frac{1}{6}\right)\)

Answer 1

(1/57 + 1/5757 + 1/23 ) . ( 1/2 - 1/3 - 1/6 )

= ( 1/57 + 1/5757 + 1/23 ) . ( 3/6 - 2/6 - 1/6 )

= (1/57 + 1/5757 + 1/23 )  .  0

= 0

Answer 2

\(\left(\frac{1}{57}+\frac{1}{5757}+\frac{1}{23}\right).\left(\frac{1}{2}-\frac{1}{3}-\frac{1}{6}\right)\)

\(=\left(\frac{1}{57}+\frac{1}{5757}+\frac{1}{23}\right).0\)

\(=0\)
