Q. Solve for z.21=zWrite your answer as a fraction.z=_____
Identify Equation & Operation: Identify the equation and the operation needed to isolate z. We have:21=zTo solve for z, we need to square both sides of the equation to eliminate the square root.
Square Both Sides: Square both sides of the equation: (\frac{\(1\)}{\(2\)})^\(2 = (\sqrt{z})^2
Perform Squaring Operation: Perform the squaring operation on both sides:(21)2=41(z)2=zSo we have:41=z
