b) \( \sqrt{9}+\sqrt{16}= \)

The expression \( \sqrt{9}+\sqrt{16} \) simplifies to \( 3 + 4 = 7 \). So, the answer is 7! Isn't it fun how square roots can turn into simple whole numbers? To make it even more interesting, square roots have been around since ancient civilizations, with the Egyptians and Babylonians using them for practical purposes like land measurement and building design. Talk about a mathematical legacy that has stood the test of time!
