Using the Associative Property of addition, if you move the parentheses anywhere between a, b, and c, the answer will always be the same. Also, the Commutative Property of addition states that if you move the terms around, the answer is also still the same. So, (a+b)+c is the same as b+(a+c).
its some t.v show I guess

after taking sqrt both side
3x/

3x/3y√2
x/√2y
multiply both denomenator and numerator by√2
√2x/2y
