Answer 2

Option (C)

Explanation:

Given question is incomplete; here is the complete question.

Consider the expression
`0.8^(x-3)` . Which of the following is an equivalent expression?

A-
`0.8^{(x)/(3)}`

B-
`0.8^{(3)/(x)}`

C-
`(0.8^(x))/(0.8^3)`

D-
`(0.8^(3))/(0.8^(x))`

Given expression is
`0.8^(x-3)`

`0.8^(x-3)=0.8^(x)* 0.8^(-3)` [Since
`x^(b+c)=x^(b)* x^(c)`]

`=(0.8x^(x))/(0.8^(3) )` [Since
`a* b^(-1)=(a)/(b)`]

Therefore, Option C will be the equivalent expression.
