Scorpion4ik [409]

Answer:

1

Step-by-step explanation:

using the rule of exponents

(\frac{a}{b}) ^{-1} = \frac{b}{a} , then

\frac{123}{321} × \frac{456}{654} × \frac{789}{987} × \frac{321}{123} × \frac{654}{456} × \frac{987}{789}

[ \frac{123}{321} × \frac{321}{123} = 1 , \frac{456}{654} × \frac{654}{456} = 1 , \frac{789}{987} × \frac{987}{789} = 1 ]

= 1 × 1 × 1

= 1
