Express each of the following as a rational number of the form `p/q :` (i)`5^(-3)` (ii) `(-2)^(-5)` (iii) `(4/3)^(-3)` (iv)`((-2)/5)^(-4)` (v) `1/(2^(-3))`

Explanation

To express each of the given expressions as a rational number of the form \( \frac{p}{q} \), we will use the property of negative exponents, which states that \( a^{-n} = \frac{1}{a^n} \) or \( \frac{b}{a^{-n}} = \frac{a^n}{b} \).

Let's solve each part step by step:

### (i) \( 5^{-3} \)

1. **Apply the negative exponent rule**:
\[
