81=9⋅9 then the square root of √81=9 . Because the double multiplication for the same sign is always positive, the square root is also valid with the other sign 81=(−9)⋅(−9) then √81=−9 and we can say that √81=±9
The 81 equals to the guitar with 14 strings and 16 frets on the project management project and I am currently working on the project management project and I am currently working on the project management project and I am currently working on the project management project and I am currently working on the project management project and I am currently working on the project management
