sqrt%2836%2Ax%5E2%29 Start with the given expression.


sqrt%2836%29%2Asqrt%28x%5E2%29 Break up the square root using the identity sqrt%28A%2AB%29=sqrt%28A%29%2Asqrt%28B%29.


6%2Asqrt%28x%5E2%29 Take the square root of 36 to get 6.


6x Take the square root of x%5E2 to get x.

==================================================

Answer:


So sqrt%2836%2Ax%5E2%29 simplifies to 6x


In other words, sqrt%2836%2Ax%5E2%29=6x where x%3E=0.
