Equivalent Expressions
1. **State the problem:** We want to find which expressions are equivalent to $$\frac{10^3}{5^3}$$.
2. **Simplify the original expression:**
$$\frac{10^3}{5^3} = \left(\frac{10}{5}\right)^3 = 2^3 = 8$$
3. **Check each option:**
- **Option 1: $$2^0$$**
- By definition, any nonzero number raised to the 0 power is 1.
- $$2^0 = 1\neq 8$$
- **Option 2: $$2$$**
- This is just 2, which is not equal to 8.
- **Option 3: $$2^3$$**
- $$2^3 = 8$$ which matches the simplified value.
- **Option 4: $$\frac{1}{2^3}$$**
- $$\frac{1}{2^3} = \frac{1}{8} \neq 8$$
4. **Final answer:** The only expression equivalent to $$\frac{10^3}{5^3}$$ is $$2^3$$.
