Answer:

• from law of indices:


\dashrightarrow \: { \tt{ \frac{a {}^(n) }{ {a}^(m) } = {a}^((n - m)) }} \\

so, • a → 675

• n → 5

• m → 8


\dashrightarrow\:{ \tt{ \frac{ {675}^(5) }{675 {}^(8) } = {675}^((5 - 8)) }} \\ \\ = { \boxed{ \boxed{ \tt{ {675}^( - 3) }}}}

\\ \rm\longmapsto (675^5)/(675^8)

  • a^m/a^n=a^m-n


\\ \rm\longmapsto 675^(5-8)


\\ \rm\longmapsto 675^(-3)

Or


\\ \rm\longmapsto (1)/(675^3)
