Pregunta

solve the exponential equation $\\sqrt{a} \\cdot \\sqrt{a} \\cdot a^3 = a^x$ for x.
options:
x equals 3
x equals 2
x equals $\\frac{2}{3}$
x equals 4

Pasos de solución

  1. Understand the question

    solve the exponential equation $\\sqrt{a} \\cdot \\sqrt{a} \\cdot a^3 = a^x$ for x.
    options:
    x equals 3
    x equals 2
    x equals $\\frac{2}{3}$
    x equals 4

  2. Explanation

    Step1: Rewrite root as exponent

    $\sqrt{a} = a^\frac{1}{2}$

    Step2: Substitute into left-hand side

    $a^\frac{1}{2} \cdot a^\frac{1}{2} \cdot a^3$

    Step3: Add exponents (same base)

    $\frac{1}{2} + \frac{1}{2} + 3 = 4$

    Step4: Equate exponents (same base)

    $a^4 = a^x \implies x=4$

  3. Final answer

    x equals 4
