Why does "j/root j" equal "1/root j"?
Good evening,
While working on the task, I can't figure out how the highlighted spot in the attached image came about. I would be extremely grateful for any clarification.
best regards

The drawing of the square root is defined in such a way that it is virtually a reversal to cuboid. That is, the square root is defined so that
[in the context of real numbers at least for all j with j ≥ 0]. Accordingly, the j )/ j the j in the denominator by (√( j )2. Then you can use the √( j ) in the counter with a √( j ) in the denominator.
Contrary
It is
The broken line was dissolved and
w(j)/j (= w(j)/(w(j) * w(j))
the
1/w(y)
It doesn't.
Root(j)/j = 1/root(j)
THERE
W(j)/j = W(j)/(W(j)*W(j)))
then shorten W(j)
Look at that again. Probably you mean the place where "Wurzel(j)/j"="1/Wurzel(j)" is set.
Expand with √j :
