To do:  Find the value of the following expression $3845\times5\times782+769\times25\times218$Solution: $3845\times5\times782+769\times25\times218$ By using BODMAS, We apply brackets to group the values that have to be multiplied.  = $( 3845 \times 5 \times 782 ) + ( 769 \times 25 \times 218)$ = $15033950 + 4191050$ = 19225000 Adding them, we get the answer, 19225000.

Any material that keeps energy such as electricity, heat, or cold from easily transferring through it is called an insulator. Wood, plastic, rubber, and glass are good insulators. 

Fauna is a term that refers to all of the animal life present in a particular region or time. The corresponding term for plants is flora. Flora, fauna, and other forms of life such as fungi are collectively known as biota.

Solution:$\frac{x}{2} - \frac{x}{3} = \frac{1}{2} + \frac{1}{4}$$\frac{3x-2x}{6} = \frac{2+1}{4}$$\frac{x}{6} = \frac{3}{4}$ $x = \frac{3}{4} \times 6 = \frac{9}{2}$ = 4.5Therefore the value of $x$ is 4.5

Leaves are green because of the presence of the pigment called Chlorophyll.It absorbs light (red and blue) for energy; the unabsorbed green bounces away and is detected by our eyes and thus appearing green.But there are so many plants that may contain multiple pigments, with different colors. While other-colored plants ... Read More

Given : The given expression is $[(\frac{-3}{2})^2]^{-3}$. To find : We have to find the value of the given expression. Solution : We know that, $(\frac{a}{b})^{m} = (\frac{a^m}{b^m})$. $[(\frac{-3}{2})^2]^{-3} =(\frac{-3^2}{2^2})^{-3} $ $= (\frac{9}{4})^{-3}$ We know that, $(\frac{a}{b})^{-m} = (\frac{b}{a})^m$. $= (\frac{4}{9})^{3}$ $= \frac{4^3}{9^3}$ $= \frac{64}{729}$ The value of $[(\frac{-3}{2})^2]^{-3}$ ...

The formula for Water is H2O.

When concentrated hydrochloric acid is added to a very dilute solution of copper sulfate, the pale blue solution slowly turns yellow-green on the formation of a copper chloride complex. 

Chromatids: The chromosome has two symmetrical structures which are called as chromatids. Each chromatid contains a single DNA molecule. At the anaphase of mitotic cell division, sister chromatids separate and migrate to opposite poles. Nucleosomes: The nucleosomes are the basic unit of chromatin with a diameter of 10 nm. The ...
