In mitosis, the prophase is further understood by dividing it into the given sub-stages:

**1.Leptotene :**

In this stage the nucleus enlarges in size in the chromosome. The chromosomes appear thin, thread-like and single-stranded in this stage. They have swollen or beaded structures along their length and their ends appear converged towards one side of the nucleus called bouquet.

**2.Zygotene:**

In this stage, the identical chromosomes come together and form bivalent or homologous pairs. Further, **...**

Log_{2a}a=x then, a=(2a)^{x } ......(1)

Log_{3a}2a=y then,2a=(3a)^{y} ......(2)

Log_{4a} 3a=z then, 3a=(4a)^{z} ......(3)

So,

a=(2a)^{x} [from (1)]

Or, a=(3a)^{xy} [from(2)]

Or, a=(4a)^{xyz} [from(3)]

Multiplying both sides by 4a,

4a.a=4a.(4a)^{xyz}

Or,(2a)² =(4a)^{xyz + 1}

Or,(3a)^{2y} =(4a)^{xyz+1}

Or,(4a)^{2yz} =(4a)^{xyz+1}

Or, 2yz = xyz+1 .proved.

The order of magnitude of a physical quantity is **its magnitude in powers of ten when the** physical quantity is expressed in powers of ten with one digit to the left of the decimal.

Orders of magnitude are generally used to make very approximate comparisons and reflect very large differences.
