Given:

The expression is

$13\sqrt {22b}-10\sqrt{22b}, b0$

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.
