- Multiplication of square root
This module is from Elementary Algebra by Denny Burzynski and Wade Ellis, Jr.
The distinction between the principal square root of the number x and the secondary square root of the number x is made by explanation and by example. The simplification of the radical expressions that both involve and do not involve fractions is shown in many detailed examples; this is followed by an explanation of how and why radicals are eliminated from the denominator of a radical expression. Real-life applications of radical equations have been included, such as problems involving daily output, daily sales, electronic resonance frequency, and kinetic energy.Objectives of this module: be able to use the product property of square roots to multiply square roots.
Overview
- The Product Property of Square Roots
- Multiplication Rule for Square Root Expressions
The product property of square roots
In our work with simplifying square root expressions, we noted that
Since this is an equation, we may write it as
To multiply two square root expressions, we use the product property of square roots.
The product property
The product of the square roots is the square root of the product.
In practice, it is usually easier to simplify the square root expressions before actually performing the multiplication. To see this, consider the following product:
We can multiply these square roots in
either of two ways:
Notice that in the second method, the expanded term (the third expression,
) may be difficult to factor into a perfect square and some other number.
Multiplication rule for square root expressions
The preceding example suggests that the following rule for multiplying two square root expressions.
Rule for multiplying square root expressions
- Simplify each square root expression, if necessary.
- Perform the multiplecation.
- Simplify, if necessary.

How bacteria create energy to survive?
Bacteria doesn't produce energy they are dependent upon their substrate in case of lack of nutrients they are able to make spores which helps them to sustain in harsh environments
_Adnan
But not all bacteria make spores, l mean Eukaryotic cells have Mitochondria which acts as powerhouse for them, since bacteria don't have it, what is the substitution for it?
Muhamad
they make spores
Louisiaste

Abreham
food webs brings about an infection as an individual depends on number of diseased foods or carriers dully.

explain assimilatory nitrate reduction
Assimilatory nitrate reduction is a process that occurs in some microorganisms, such as bacteria and archaea, in which nitrate (NO3-) is reduced to nitrite (NO2-), and then further reduced to ammonia (NH3).
Elkana
This process is called assimilatory nitrate reduction because the nitrogen that is produced is incorporated in the cells of microorganisms where it can be used in the synthesis of amino acids and other nitrogen products
