Answer 1

Answer:

${( \frac{ {x}^{b} }{ {x}^{c} }) }^{2} ( { \frac{ {x}^{c} }{ {x}^{a} }) }^{b} ( { \frac{ {x}^{a} }{ {x}^{b} }) }^{c}$

$= ( { {x}^{b - c} )}^{a} ( { {x}^{c - a}) }^{b} ( { {x}^{a - b}) }^{c}$

$= {x}^{ab - ab} \times {x}^{bc - ab} \times {x}^{ac - bc}$

$= {x}^{ab - ac + bc - ab + ac - bc}$

$= {x}^{0}$

$= 1$
