Question

What is the square root of 8+b

Answer 1

$\sqrt{8+b} = \sqrt{8} * \sqrt{b} = \sqrt{4*2} * \sqrt{b} =2 \sqrt{2}* \sqrt{b} =2 \sqrt{2b}$

Answer 2

The answer is the square root of  (√ 8 + b),  because you are adding two terms that can not be combined because you do not know the value of be, so that is the simplest form √8 +b
