\( 2^{2}+4^{2}=\square \) Question Help: \( \square \) Video \( \square \) Message instructor

Let’s break it down! First, calculate \( 2^{2} \), which equals 4. Next, calculate \( 4^{2} \), which equals 16. Now add them together: \( 4 + 16 = 20 \). So, \( 2^{2}+4^{2}=20 \)! Now, here's a fun tidbit: Pythagorean triples, like \( 3^2 + 4^2 = 5^2 \), are foundational in geometry and give us insight into right-angled triangles. Understanding these can help in various real-world applications, such as construction and navigation, ensuring structures are solid and routes are efficient!
