If
$\text{\hspace{0.17em}}a\text{\hspace{0.17em}}$ and
$\text{\hspace{0.17em}}b\text{\hspace{0.17em}}$ are nonnegative, the square root of the product
$\text{\hspace{0.17em}}ab\text{\hspace{0.17em}}$ is equal to the product of the square roots of
$\text{\hspace{0.17em}}a\text{\hspace{0.17em}}$ and
$\text{\hspace{0.17em}}b.\text{\hspace{0.17em}}$
$\sqrt{ab}=\sqrt{a}\cdot \sqrt{b}$
Given a square root radical expression, use the product rule to simplify it.
Factor any perfect squares from the radicand.
Write the radical expression as a product of radical expressions.
$5\left|x\right|\left|y\right|\sqrt{2yz}.\text{\hspace{0.17em}}$ Notice the absolute value signs around
x and
y ? That’s because their value must be positive!
Just as we can rewrite the square root of a product as a product of square roots, so too can we rewrite the square root of a quotient as a quotient of square roots, using the
quotient rule for simplifying square roots. It can be helpful to separate the numerator and denominator of a fraction under a radical so that we can take their square roots separately. We can rewrite
$\text{\hspace{0.17em}}\sqrt{\frac{5}{2}}\text{\hspace{0.17em}}$ as
$\text{\hspace{0.17em}}\frac{\sqrt{5}}{\sqrt{2}}.$
The quotient rule for simplifying square roots
The square root of the quotient
$\text{\hspace{0.17em}}\frac{a}{b}\text{\hspace{0.17em}}$ is equal to the quotient of the square roots of
$\text{\hspace{0.17em}}a\text{\hspace{0.17em}}$ and
$\text{\hspace{0.17em}}b,$ where
$\text{\hspace{0.17em}}b\ne 0.$
$\sqrt{\frac{a}{b}}=\frac{\sqrt{a}}{\sqrt{b}}$
Given a radical expression, use the quotient rule to simplify it.
Write the radical expression as the quotient of two radical expressions.
$\frac{x\sqrt{2}}{3{y}^{2}}.\text{\hspace{0.17em}}$ We do not need the absolute value signs for
$\text{\hspace{0.17em}}{y}^{2}\text{\hspace{0.17em}}$ because that term will always be nonnegative.
We can add or subtract radical expressions only when they have the same radicand and when they have the same radical type such as square roots. For example, the sum of
$\text{\hspace{0.17em}}\sqrt{2}\text{\hspace{0.17em}}$ and
$\text{\hspace{0.17em}}3\sqrt{2}\text{\hspace{0.17em}}$ is
$\text{\hspace{0.17em}}4\sqrt{2}.\text{\hspace{0.17em}}$ However, it is often possible to simplify radical expressions, and that may change the radicand. The radical expression
$\text{\hspace{0.17em}}\sqrt{18}\text{\hspace{0.17em}}$ can be written with a
$\text{\hspace{0.17em}}2\text{\hspace{0.17em}}$ in the radicand, as
$\text{\hspace{0.17em}}3\sqrt{2},$ so
$\text{\hspace{0.17em}}\sqrt{2}+\sqrt{18}=\sqrt{2}+3\sqrt{2}=4\sqrt{2}.$
Given a radical expression requiring addition or subtraction of square roots, solve.

I think the formula for calculating algebraic is the statement of the equality of two expression stimulate by a set of addition, multiplication, soustraction, division, raising to a power and extraction of Root. U believe by having those in the equation you will be in measure to calculate it
the Cayley hamilton Theorem state if A is a square matrix and if f(x) is its characterics polynomial then f(x)=0 in another ways evey square matrix is a root of its chatacteristics polynomial.
