Find the square root. 1600′ The Correct Answer and Explanation is: Answer: The square root of 1600 is 40. Explanation To find the square root of a number means to determine what number, when multiplied by itself, equals the original number. In mathematical terms, ifx2=1600,x^2 = 1600,x2=1600, thenx=1600.x = \sqrt{1600}.x=1600​. Let’s go step-by-step. First, recognize

What is the square root of 1600? The Correct Answer and Explanation is: Correct Answer:The square root of 1600 is 40. Explanation: To find the square root of a number means to determine what number, when multiplied by itself (squared), gives the original number. In other words, if x2=1600x^2 = 1600×2=1600, then xxx is the
