( \frac{5 ^{a} }{5 ^{b} }) ^{a + b} ( \frac{5 ^{b} }{5 ^{c} }) ^{b + c} ( \frac{5 ^{c} }{5 ^{a} }) ^{c + a}

 = ( {5}^{a - b} ) {}^{a + b} ( {5}^{ b - c} ) {}^{c + b} ( {5}^{c - a} ) {}^{a + c}

 = ( {5}^{ {a}^{2}  -  {b}^{2} } )( {5}^{ {b}^{2}  -  {c}^{2} } )( {5}^{ {c}^{2} -  {a}^{2}  } )

 =  {5}^{ {a}^{2}  -  {b}^{2}  +  {b}^{2}  -  {c}^{2}  +  {c}^{2}  -  {a}^{2} }

 =  {5}^{ \cancel{{a}^{2} } -  \cancel{{b}^{2}  }+  \cancel{{b}^{2} } - \cancel{ {c}^{2}}  +\cancel{  {c}^{2} } -  \cancel{{a}^{2}} }

 =  {5}^{0}

 = 1
