Square rooting powers
WebOnly positive numbers can have their square roots taken, without using imaginary numbers. Negative numbers can have their cube roots taken. Knowing the square roots of perfect squares and the exponential rules is very useful when evaluating or simplifying algebraic expressions containing powers and roots. Web27 Jan 2015 · In your case, you have squaring, followed by addition, followed by a square root. This is significant figures followed by decimal places followed by significant figures, so we must round at each step. First is squaring, which uses significant figures. If you think of this as powers, the $2$ is exact and does not affect the precision of the answer.

WebAs we just saw, putting minuses in front of a and b changes the direction of the inequality. This is called the "Additive Inverse": If a < b then −a > −b. If a > b then −a < −b. This is really the same as multiplying by (-1), and that is why it changes direction. Example: Alex has more money than Billy, and so Alex is ahead.
