Theory:

When dividing degrees with the same base, the powers are subtracted, and the base remains unchanged.
 
an:am=anm

Where a0, \(n\) and \(m\) are natural numbers such that n>m.
Important!
You cannot replace the value of the difference a15a4 on a11.
The formula is applied from left to right, and from right to left.
Example:
Calculate:
1. 53:5

Answer: 53:5=53:51=531=52=25.
 
  
2. 37:33.
Answer: 37:33=373=34=81.
 
  
3. Simplify the expression. t27t14.
Answer:t27t14=t27:t14=t2714=t13.
 
  
4. Make 27 as a ratio.
Answer: Exponent \(7\) can be represented as a difference in several ways:
27=292=29:22;27=281=28:21=28:2.
