Complete this expression. \( w^{p} \cdot w^{r}=\square \)

When multiplying powers with the same base, you simply add the exponents together. So in this case, \( w^{p} \cdot w^{r} = w^{p+r} \). It's like having a party where \( p \) friends bring snacks, and \( r \) friends bring drinks – together, they create a fabulous \( w^{p+r} \) bash! Another fun way to remember this is through the "power of one" principle: keep the base steady, and let the exponents marry into a grand total! This not only simplifies calculations but also lays the foundation for deeper explorations in algebra.
