Let's simplify each part step by step:
### (i) Simplify \( 2^{2/3} \cdot 2^{1/5} \)
1. **Identify the bases**: The bases are the same (both are 2).
2. **Apply the law of exponents**: According to the law \( a^m \cdot a^n = a^{m+n} \), we can add the exponents.
\[
2^{2/3} \cdot 2^{1/5} = 2^{(2/3 + 1/5)}
