$\huge\boxed{\texttt{\fcolorbox{Red}{aqua}{Hey Mate!!!}}}$
$\frac{125 \times 5 {}^{ - 3} \times t {}^{ - 8} }{625 \times 5 {}^{ - 4} \times t {}^{ - 4} } \\ = \frac{5 {}^{3} \times 5 {}^{ - 3} \times t {}^{ - 8} }{5 {}^{4} \times 5 {}^{ - 4} \times t {}^{ - 4} } \\ = t {}^{ - 8 + 4} \\ = t {}^{ - 4} \\ = \frac{1}{t {}^{4} }$
