Beyond the Answer
To find the square of \( 3 \sqrt{17} \), you simply multiply \( 3 \sqrt{17} \) by itself. This gives you \( 9 \times 17 = 153 \). So, the square is \( 153 \) or \( (3 \sqrt{17})^2 = 153 \). For the square root of \( 36 x^5 y^2 \), you split it into the square roots of the constants and the variables. The square root of \( 36 \) is \( 6 \), the square root of \( x^5 \) is \( x^{2} \) (taking \( x^4 \) out as \( x^2 \) and leaving \( x \) inside), and \( y^2 \) becomes \( y \). So, you get \( 6 x^2 y \).
