you can simply use the caret symbol ^ and get 4^2
or if you are typing into a program or form that supports Unicode you can hold alt and press 0178 to get 4²
for typing in a form that supports html you can put the two in the <sup>2</sup> tags and the output will still look like 42
Change the font style of the 4 to 'superscript'
2
-4 to the second power is 16
12 to the second power is 144...2 to the second power is 4, any # to the second power is the # times itself.
Calculate the powers, and do the addition. For example, the second power of 4 is the same as 4 x 4 (you are supposed to multiply 4 by itself).
You would either use the superscript feature if there is one, or a caret and then the 4. For instance: X4 or X^4
4,096 or 4 to the sixth power. When multiplying numbers with powers you add the powers if the whole number is identical. 4 squared x 4 squared is 64, x 4 squared is 4096
4 to the second power
4 x 4 = 16
The answer is 256.
(-4)(-4) or (-4)2
