    Given:

    The expression is

    13\sqrt {22b}-10\sqrt{22b}, b>0

    To find:

    The equivalent expression.

    Solution:

    We have,

    13\sqrt {22b}-10\sqrt{22b}

    Taking out common factors.

    =(13-10)\sqrt {22b}

    =(3)\sqrt {22b}

    =3\sqrt {22b}

    The expression 3\sqrt {22b} is equivalent to the given expression.

    Therefore, the correct option is D.
