Let's simplify the first problem step by step! 🎉
**Problem 1:** $\sqrt{327} + \sqrt{50} - \sqrt{7}$
**Step 1:** Break down each square root to see if we can find a perfect square inside.
$\sqrt{327}$: 327 = 3 \times 109 (no perfect squares inside)
$\sqrt{50}$: 50 = 25 \times 2, and $\sqrt{25} = 5$, so $\sqrt{50} = 5\sqrt{2}$
$\sqrt{7}$: 7 is prime, so it stays $\sqrt{7}$
**Step 2:** Rewrite the expression:
$\sqrt{327} + 5\sqrt{2} - \sqrt{7}$
**Step 3:** Since $\sqrt{327}$ can't be simplified easily, the answer is:
$\sqrt{327} + 5\sqrt{2} - \sqrt{7}$
Great! We simplified what we could! 🌟
