O(n) denotes the orthogonal group, the subgroup of GLn(R) consisting of all real orthogonal n × n matrices. These are the rotations and reflections of R n that fix the origin. Find the orbits of the O(2)-action on R 2 . For a point (x, y) ∈ R 2 what is its stabilizer?

The answer is 765783.0000000000000000

Step-by-step explanation:

That's what the calculator said

The answer of given expression in simplest form is:    

The given expression is:

Multiplying negative sign with negative sign will result in positive sign of the latter term.

The simplification will be done as follows:

In the above process, we the lcm of 8 and 20 was taken which is equal to 40.

Thus, the simplest form of the given expression is .
