Let take that 3 + 2√5 is a rational number.
So we can write this number as
3 + 2√5 = a/b
Here a and b are two co prime number and b is not equal to 0
Subtract 3 both sides we get
2√5 = a/b – 3
2√5 = (a-3b)/b
Now divide by 2 we get
√5 = (a-3b)/2b
Here a and b are integer so (a-3b)/2b is a rational number so √5 should be a rational number But √5 is a irrational number so it contradict the fact
Hence result is 3 + 2√5 is a irrational number

Chemical evolution |
Organic evolution |
|
1. It occurs due to changes in the structure of molecules; from complex molecules to simple molecules with the passage of time. |
1. It occurs due to changes in a species which appear generation after generation and accumulate to form a new species. |
|
2. It is a relatively fast process and hence, it is possible to prove it in a laboratory. |
2. It is a very slow process and hence, it is impossible to prove it in a laboratory. |
|
3. It involves the evolution of chemicals such as water vapour, methane, ammonia and hydrogen into organic molecules such as sugars which later combined to form big molecules such as proteins, RNA and DNA. |
3. It involves the evolution of enzymes, proteins, RNA and DNA into membrane bound proto cells and finally into living cells. |
|
4. Chemical evolution came into being before organic evolution. |
4. Organic evolution is a consequence of chemical evolution. |

| Has only one ingredient – Sodium Bicarbonate | Consists of many ingredients including Bicarbonates (typically baking soda), and acid salts. |
| Does not contain Monocalcium Phosphate | Contain Monocalcium Phosphate, which reacts with NaHCO3 when wetted and heated. |
| Reacts immediately with acids | It does not immediately react when exposed to acids. |
| Short leavening process | The leavening process extended with the help of a second acid. |
| Baking products formed when baking soda is used are not as fluffy when compared to baking powder products, due to shorter reaction duration. | Gives fluffier products from baking |
