Dear students Differentiate x power underroot 2 with respect to x. Got rewarded by answering early.
first take y= x^(root 2) then taking log both the sides log y= (root 2) log x now diff w.r.to x 1/y (dy/dx)= (root 2) 1/x so dy/dx= y (root 2/x) now by putting y's value here dy/dx= x^(root 2)* (root 2/x)

__________ of the following statements is not correct. (the law of physics are the same in all inertial frames, the speed of light in free space has the same value in all inertial frames, two events which occur simultaneously in one reference frame also must appear to occur simultaneous in another reference frame, Einstein rejected Newton’s idea of absolute time)
