WebRoots are the inverse operation to powers. So if you take the square root of 6 and then you square it, then you would be left with 6 because the square and the square root cancel out. Now if you have the square root of 2 plus the square root of 2, you would have 2√2. Notice that it isn't √4. It is actually 2√2 (which is the same as √8). Webx = +/ − \( \mathbf{^3 ... (-2)³ means (-2 × -2 × -2) = -8; You can see you'll always get a negative result with an odd exponent and a negative sign, whether it's inside or outside of parentheses. But when you have an even exponent the result depends on the interpretation of the negative sign and the presence of parentheses ...
