Question

Please help me answer this question
Explain how you got your answer

Answer 1

• 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) }}}}`

Answer 2

`\\ \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)`
