The answer would be 656.
Extracting the root is the inverse operation of ^2:
<span><span>656<span>−−−</span>√2</span>×<span>656<span>−−−</span>√2</span>=<span><span>656<span>−−−</span>√2</span>2</span>=656</span>
The term can be written as
<span><span>656<span>−−−</span>√</span>or<span>656<span>−−−</span>√2</span></span>
Like any positive number, the number 656 has two square roots: <span>656<span>−−−</span>√2</span>
, which is positive and called principal square root of 656, and −<span>656<span>−−−</span>√2</span>
, which is negative.
Together, they are denominated as ± <span>656<span>−−−</span>√2</span>
.Hope this helps!!
