WebYes, square roots can create 2 answers -- the positive (principal) root and the negative root. When you are working with square roots in an expression, you need to know which value you are expected to use. The default is the principal root. We only use the negative root when there is a minus in front of the radical. For example: 8 + sqrt (9) = 11 WebThe root mean square of a data set is exactly what it sounds like: it is the result of the square root of the mean of each item in a data set squared. There are specific applications for this, such as when trying to find the mean of an alternating data set, where the raw mean would always be 0. In the physics of gas molecules, the root-mean-square speed is defined as the square root of the average squared-speed.

WebWhen you simplify a square root, you need to ensure you have removed all perfect squares. With 3√8, you still have a perfect square inside the radical. 3√8 = 3√(4*2) = 3√4 * √2 = 3*2√2 = 6√2 Hope this helps. 1 comment Comment on Kim Seidel's post “Yes, you can take … WebFeb 1, 2024 · Accepted Answer.
