Web7. Point out that to “simplify” a square root with a variable, “absolute value” symbols are necessary when the variable has an “even” exponent and the exponent of its square root is “odd.” For example in x4 = x2, since “x” is squared in the answer, it will automatically be positive. In x6 = x3, in order to solve for opposite side of right triangleWebMar 16, 2024 · Community Answer. When you multiply a whole number by a square root, you just put the two together, with the whole number in front of the square root. For example, 2 * (square root of 3) = 2 (square root of 3). If the square root has a whole number in front of it, multiply the whole numbers together. solve for r. show your workWebJul 25, 2024 · Since squaring a quantity and taking a square root are ‘opposite’ operations, we will square both sides in order to remove the radical sign and solve for the variable inside.
