WebApr 3, 2024 · The square root function, by definition, is a function whose values are all nonnegative. So the algebraic step is related to taking square roots, but it's not the same as taking square roots. Indeed, the pedentically correct formulation of the "square root" algebraic step is this: x 2 = y 2 if and only if x = y . WebSquare both sides, and x^2 = 4. For some reason, if you want to take the square root of both sides, and you get x= +/- 2, because -2 squared is still equal to four. But, according to the original equation, x is only equal to 2. Therefore -2 is an extraneous solution, and …

The addition or … WebThe general guideline of writing the square root as a fractional power and then using the power and chain rule appropriately should be fine however. Also, remember that you can simply pull out a constant when dealing with derivatives - see below. If g ( x) = 2 x = 2 x 1 / 2. Then, g ′ ( x) = 2 ⋅ 1 2 x − 1 / 2. g ′ ( x) = 1 x 1 / 2 = 1 x. lebron more than a game full movie
