5m - 3n = 19 ......... (i)
m - 6n = -7 ........... (ii)
Multiple (i) by 2 , we get
10m - 6n = 38........... (iii)
Subtract (iii) and (ii), we get
(10m - 6n)- (m - 6n) = 38 - (-7)
10m - 6n - m + 6n = 38 + 7
9m = 45
m = 5
Put m = 5 in (ii) we get
5 - 6n = -7
-6n = -7 - 5
-6n = -12
n = 2

Any number can be written as the product of a number between 1 and 10 and a number which is power of ten. The exponential part of a particular measurement is called order of magnitude of a quantity.
Example: Diameter of Jupiter = 142700000 m = 1.427 x 108 m
Order of magnitude = exponential part = 108 m

3x + 2y = 29 .......... (i)
5x - y = 18 .......... (ii)
multiply equation (ii) by 2 and add in (i) , we get
3x + 2y = 29
+10x - 2y = 36
____________
13x=65
x = 65/13= 5
now put in (ii), we get
5(5) - y = 18
25 - y = 18
25 - 18 = y
7 = y
and x = 5

Freezing point depressionΔTf = i × Kf × mi = ΔTf Kf × m = 7.10 × 10−31.86 × 0.001 =3.82 ≈ 4The total number of value of i = 4The given complex Kx[Fe(CN)6] has already complex ion [Fe(CN)6] as 1.So the remaining are K ions = 4−1 = 3Thus the value of x =3 and the complex is K3[Fe(CN)6]

Cells are similar to small factories with different laborers and departments that work all the time to make life possible. Various kinds of cells perform different functions like protein synthesis and energy production.There are two major kinds of living organisms based on their cellular structure namely: prokaryotes and eukaryotes.
- Prokaryotes are made up of cells with no nucleus. They all are single-celled microorganisms including archaea, bacteria and photosynthetic blue-green algae which are also known as cyanobacteria.
- Eukaryotes consists of cells with a nucleus. This large category involves all plants, fungi (such as molds, yeast, and mushrooms), protozoa (Plasmodium falciparum and parasite that cause malaria) and animals. The plasma membrane is responsible for monitoring the transport of nutrients and electrolytes in and out of the cell and also responsible for cell to cell communication.

(a+b) ^2 means (a+b)*(a+b)
So (a+b)*(a+b)=a*(a+b) <i>+</i> b*(a+b)
On solving the brackets :
a*(a+b) <i>+</i> b*(a+b)
=(a*a) +(a*b) <i>+</i>(b*a) +(b*b)
=a^2 + ab <i>+</i> ba + b^2
=a^2 + 2ab + b^2
So, (a+b) ^2 = a^2 + 2ab + b^2
