Option (C)

Step-by-step 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- $0.8^{\frac{x}{3}}$

B- $0.8^{\frac{3}{x}}$

C- $\frac{0.8^{x}}{0.8^3}$

D- $\frac{0.8^{3}}{0.8^{x}}$

Given expression is $0.8^{x-3}$

$0.8^{x-3}=0.8^{x}\times 0.8^{-3}$ [Since $x^{b+c}=x^{b}\times x^{c}$ ]

$=\frac{0.8x^{x}}{0.8^{3} }$ [Since $a\times b^{-1}=\frac{a}{b}$ ]

Therefore, Option C will be the equivalent expression.
