[tex]the \: ans = \boxed{\frac{1}{5 {}^{15} } }[/tex]
Step-by-step explanation:
[tex]since \: anything \: raised \: to \: power \: (- whatever) \: is \: same \: as \to \frac{1}{anything \: raised \: to \: power \: whatever} \\ so \to \: x {}^{ - 8} = \frac{1}{ {x}^{8} } \\ \\ hence \to \boxed{ {5}^{ - 15} = \frac{1}{5 {}^{15} } }[/tex]
