Question

Simplify

Answer 1

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
