Which expression is equivalent to 13√22b - 10√22b , if b > 0?

Step-by-step explanation:

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.

over the argument its not good to fight.

i agree because i see the other persons thinking is clear
