The value of the cube root of 22 rounded to 4 decimal places is **2.802**. It is the real solution of the equation x^{3} = 22. The cube root of 22 is expressed as ∛22 in the radical form and as (22)^{⅓} or (22)^{}^{.}^{33} in the exponent form.

Select the “^” symbol located on the top row. Press the **“123” icon** located on the lower left side of the keyboard. Press the number “2.” You have now written a squared symbol.

We can say that **the square root and the square cancel each other out**. They are the inverse of each other. If we have a number written with the index 2 ( squared) then taking the square root simply means that we leave out the 2 ( this only applies to positive numbers ).

X²-Y²**=(X+Y)(X-Y)**

Answer: x squared plus x squared is **2x ^{2}**.

The difference of squares, x² – y², can be factored as the product of the sum and difference of two terms, or **x² – y² = (x + y)(x – y)**. Example: 2×2 – 18 = 2(x² – 9), = 2(x – 3)(x + 3).
