You're absolutely correct, jeongethan.jeongethan wrote:(root2)/ 4 + 3/ 2(root2) = ?
I got root 2 but not sure ;(
shame on me
Given:(root2)/4 + 3/(2root2)
To add these fractions, we need common denominators. If we take 3/(2root2) and multiply top and bottom by root2, we get:
(root2)/4 + (3root2)/(2root4), which equals (root2)/4 + (3root2)/4
Now that we have common denominators, we can add the numerators, to get (4root2)/4.
When we cancel out the 4's, we get root2
