^

what does that sign mean?

for example:
2a^2 = 14^2 = 196
a^2 = 98
a = sqrt (98)=7 sqrt (2)
perimiter = 4 a = 28 sqrt (2) inches =
about 40 inches

It indicates "to the power"
^2 indicates to the power 2 or square
so a^2 means a squared
cm^2 means cm squared or square centimeter
x^3 means x to the power 3 or x cubed

2a^2 means that a is squared, or raised to the 2nd power. In orders of operators, powers are performed before multipliers.

In print, a squared function is represented by a superscript 2, but in computer spreadsheets, there was no corresponding operator. So it was created by using the caret, ^, to represent a number raised to the power which follows the caret.

If a=7, then 7 squared = 49. Multiplying it by 2 makes it 98.

By the way, it's also handy for doing square roots. A square root is simply a number raised to the 1/2 power. In other words, 25^.5 = 5.

^ means raised to the power of

It is difficult to type in an expression with exponents, so that symbol is used, as well as the square root symbol; instead it is expressed here as square root of 98.

3^2 = 3² = 9. ^ is how you write an exponent in many computer languages, and how you have to write it when your text editor can't do superscripts.

a^2 is a raised to the power of 2
a^3 """"""""""""""""""""""""""""""""3
a^7"""""""""""""""""""""""""""""""""7
etc

2 a ² = 196
a ² = 98
a ² = 49 x 2
a = 7√2
If perimeter = 4a, then:-
p = 28√2 = 39.6 (to 1 dec. place)
