The opposite of a square root is the square of a number. In mathematical terms, if the square root of a number x is denoted as √x, then the opposite of the square root (√x) is x itself. This is because squaring a number undoes taking the square root of that number.
The inverse operation of squaring a number is finding the square root of that number. In mathematical terms, if you square a number x, the result is x^2. The inverse operation would be taking the square root of x^2, which gives you the original number x. For example, if you square 3 (3^2 = 9), the square root of 9 is 3.
If you want to know how to square a trinomial, you should first know the basic. (a+b+c)^2=? you have to square the first three terms then multiply 2 to the last three terms. All you have to do is to remember that a square of trinomial has 6 terms in the answer
20 = 20(1/2) x 20(1/2) = 4.4721359549995824.4721359549995793928183473374626
To simplify the expression 2a^2b^2 + 5ab^2 + 8a^2b^2 - 3ab^2, first combine like terms. The terms with a^2b^2 are 2a^2b^2 + 8a^2b^2 = 10a^2b^2. The terms with ab^2 are 5ab^2 - 3ab^2 = 2ab^2. Therefore, the simplified expression is 10a^2b^2 + 2ab^2.
