On a computer, there should be a letter X with the number 2 in the exponent position. It should look like this: x2
In writing, you just mark it near the top right hand corner of the number or variable.
The two squared numbers that add together to make 80 are 64 (which is (8^2)) and 16 (which is (4^2)). Therefore, (8^2 + 4^2 = 64 + 16 = 80).
It is 8
-3 squared by 2
-2 squared is +4.
You could just pull out the half: it will be (1/2) cos squared x.
The exponent "2" as in a number squared, e.g. cm2 or in2
No, three squared is nine. 3(squared sign) =3x3 =9
They are terms of an expression because without an equality sign it is not an equation.
The two squared numbers that add together to make 80 are 64 (which is (8^2)) and 16 (which is (4^2)). Therefore, (8^2 + 4^2 = 64 + 16 = 80).
a^2b^2c^2 ^2 is squared
The symbol for squared is ², for example, 2 squared would be 2².
You don't. You put a cubed sign for volume, which surface area is not. Surface area gets a squared sign. The reason for THAT is to show it's a 2-dimensional measurement.
The result of a number multiplied by itself
It is 8
-2 squared is +4.
-3 squared by 2
You could just pull out the half: it will be (1/2) cos squared x.
