Google : Hold the alt key and click the following numbers by clicking 0,1,7,8.
Microsoft Document: Click "alt" gear and type in 2, 5, 3 and there you have it!!

Any number, A, raised to some power, x, can be written in the form, A^x in keyboard form.E.g. five squared would be written 5^2.
You must use character map to type out the abbreviated form of partial eta squared (ηρ²) since it uses Greek letters which are not included on an English based keyboard.
Use the caret (shift 6). eg 3 squared can be typed as 3^2.
Unfortunately you cannot writ a sq. root symbol on the computer, so you could just say 'squared.'
There is a shortcut to making ² symbol, and it is Alt0178, which is hold down Alt button and while held down type 0178 numbers then release Alt button. Maybe there are special keyboards that can be bought that have it included; not sure.
The generally accepted way to type powers of a number is by using the carat symbol, or "^." So five to the second power (or squared) is 5^2.
he made the theorem C squared = A squared + B squared and A squared = C squared - B squared or B squared = C squared - A squared
You can ask your math teacher
9x squared-15x squared = -6
2 squared X 3 squared = 5 squared
1 squared = 1 2 squared = 4 3 squared = 9 4 squared = 16 5 squared = 25 6 squared = 36 7 squared = 49 8 squared = 64 9 squared = 81 10 squared = 100
100cm squared = 0.01 metres squared
