Question
Simplify: $\Big(\frac{\text{x}^{\text{a}+\text{b}}}{\text{x}^\text{c}}\Big)^{\text{a}-\text{b}}\Big(\frac{\text{x}^{\text{b}+\text{c}}}{\text{x}^\text{a}}\Big)^{\text{b}-\text{c}}\Big(\frac{\text{x}^{\text{c}+\text{a}}}{\text{x}^\text{b}}\Big)^{\text{c}-\text{a}}$

Answer

$\Big(\frac{\text{x}^{\text{a}+\text{b}}}{\text{x}^\text{c}}\Big)^{\text{a}-\text{b}}\Big(\frac{\text{x}^{\text{b}+\text{c}}}{\text{x}^\text{a}}\Big)^{\text{b}-\text{c}}\Big(\frac{\text{x}^{\text{c}+\text{a}}}{\text{x}^\text{b}}\Big)^{\text{c}-\text{a}}$
$=\big(​​\text{x}^{\text{a}+\text{b}+\text{c}}\big)^{\text{a}-\text{b}}\big(\text{x}^{\text{b}+\text{c}+\text{a}}\big)^{\text{b}-\text{c}}\big(\text{x}^{\text{c}+\text{a}-\text{b}}\big)^{\text{c}-\text{a}}$
$=\text{x}^{(\text{a}-\text{b})(\text{a}+\text{b}-\text{c})}\times\text{x}^{(\text{b}-\text{c})(\text{b}+\text{c}-\text{a})}\times\text{x}^{(\text{c}-\text{a})(\text{c}+\text{a}-\text{b})}$
$=\text{x}^{\text{a}^\text{2}+\text{ab}-\text{ac}-\text{ab}-\text{b}^\text{2}+\text{bc}}\times\text{x}^{\text{b}^\text{2}+\text{bc}-\text{ab}-\text{bc}-\text{c}^2+\text{ac}}\times\text{x}^{\text{c}^2+\text{ac}-\text{bc}-\text{ac}-\text{a}^\text{2}+\text{ab}}$
$=\text{x}^{\text{a}^2-\text{ac}-\text{b}^2+\text{bc}}\times\text{x}^{\text{b}^2-\text{ab}-\text{c}^2+\text{ac}}\times\text{x}^{\text{c}^2-\text{bc}-\text{a}^2+\text{ab}}$
$=\text{x}^{\text{a}^2-\text{ac}-\text{b}^2+\text{bc}+\text{b}^2-\text{ab}-\text{c}^2+\text{ac}+\text{c}^2-\text{bc}-\text{a}^2+\text{ab}}$
$=\text{x}^0$
$=1$
