1 Answer

  1. Let’s evaluate each value of x to see if it solves either equation:

    1. x = √30:

    – For x² = 30: (√30)² = 30 (True)

    – For x³ = 30: (√30)³ = 30√30 (False)

    – Result: Solution of x² = 30.

    2. x = 3√30:

    – For x² = 30: (3√30)² = 9 * 30 = 270 (False)

    – For x³ = 30: (3√30)³ = 27 * 30√30 = 810√30 (False)

    – Result: Neither.

    3. x = −√30:

    – For x² = 30: (−√30)² = 30 (True)

    – For x³ = 30: (−√30)³ = -30√30 (False)

    – Result: Solution of x² = 30.

    4. x = −3√30:

    – For x² = 30: (−3√30)² = 9 * 30 = 270 (False)

    – For x³ = 30: (−3√30)³ = -27 * 30√30 = -810√30 (False)

    – Result: Neither.
