Finding the square root of non-perfect squares
You can estimate its value by finding the two perfect squares that the number is between: is between which is 7 and which is 8 so we know that the square root of 50 is between 7 and 8, my estimate would be closer to 7 because 50 is so much closer to 49 than it is to 64. I would estimate, 7.1
You can also use a calculator or a table of values to find the answer to the nearest thousandth. Every calculator is different, you must use the √ symbol; see your teacher for further clarification. Using a calculator the = 7.071.
