Question

Solve the radical equation cube root of x minus 1 end root equals 2

hintHint:

Rearrange the equation and then solve for x.

The correct answer is: ⇒ x = 9


    Complete step by step solution:
    Here given equation is cube root of x minus 1 end root equals 2
    not stretchy rightwards double arrow left parenthesis x minus 1 right parenthesis to the power of 1 third end exponent equals 2
    On cubing both the sides, we have open parentheses left parenthesis x minus 1 right parenthesis to the power of 1 third end exponent close parentheses cubed equals 2 cubed
    rightwards double arrow x minus 1 equals 8
rightwards double arrow x equals 9

    A second-degree quadratic equation is an algebraic equation in x. Ax² + bx + c = 0, where 'x' is the variable, 'a' and 'b' are the coefficients, and 'c' is the constant term, is the quadratic equation in its standard form. A non-zero term (a ≠ 0) for the coefficient of x² is a prerequisite for an equation to be a quadratic equation. The x² term is written first, then the x term, and finally, the constant term is written when constructing a quadratic equation in standard form. In most cases, the numerical values of a, b, and c are not expressed as decimals or fractions but are written as integral values. There are a maximum of two solutions for x in the second-degree quadratic equations. These two solutions for x are referred to as the quadratic equations' roots and are given the designations (α, β). There are several ways to present the quadratic equations: (x - 1)(x + 2) = 0, 5x(x + 3) = 12x, x³ = x(x² + x - 3), where -x²= -3x + 1. Before carrying out any additional procedures, these equations are to be translated into the quadratic equation's standard form.
