Inverse of sine squared

In a book that I am using, it is written that " 7 sin^2x-1=0 turns into x=sin^-1 +-(square root of)1/7.

If I want to move sin^2 to the other side, is it right for the sine to be turned into the inverse of sine or sin^-1?

If it is right, what is the rule of math that covers this?

Thank you in advance for your hospitality.
