Solving the Mystery of Square Root x Multiplied by 1/x

Click For Summary
SUMMARY

The equation √x * (1/x) simplifies to 1/√x through algebraic manipulation. By letting y = √x, we establish that x = y². Thus, √x/x becomes y/y², which simplifies to 1/y, and since y = √x, this results in 1/√x. This clarification resolves the confusion surrounding the mathematical identity.

How is squareroot(x)*(1/x)= 1/square root x

can somebody please explain this? I think I am having a brain lockup...

Let y=√x, the x=y². So √x/x = y/y² = 1/y = 1/√x.

Thank you! For some reason I couldn't think of the reason to make the statement true.

Life saver!
