1. ab x ac = ab+c
Example: 2 x 22 = 21+2 = 23
2. ab ÷ ac = ab-c
Examples:
35 ÷ 32 = 35-2 = 33
32 ÷ 35 = 32-5 = 3-3
3. a-b = 1/ab
Example: 3-3 = 1/33
The laws of exponents work the same with rational exponents, the difference being they use fractions not integers.
Combining laws of exponents refers to the rules that govern the manipulation of expressions involving powers. Key laws include the product of powers (adding exponents when multiplying like bases), the quotient of powers (subtracting exponents when dividing like bases), and the power of a power (multiplying exponents when raising a power to another power). These rules help simplify expressions and solve equations involving exponents efficiently. Understanding these laws is essential for working with algebraic expressions in mathematics.
That depends how you choose to number the laws.

This is one of the laws of exponents, which states that xa * xb = x(a+b) The base is x, and the two powers (or exponents) are a and b.

Exponents are used in many different contexts and for different, though related, reasons. Exponents are used in scientific notation to represent very large and very small numbers. The main purpose it to strip the number of unnecessary detail and to reduce the risk of errors. Exponents are used in algebra and calculus to deal with exponential or power functions. Many laws in physics, for example, involve powers (positive, negative or fractional) of basic measures. Calculations based on these laws are simper if exponents are used.
The answer to your question is derived from the Laws of Exponents. According to these laws when you encounter exponents in division problems you perform a subtraction. (Ex. a2/a3) After subtracting the exponents (2-3= -1) you are left with an exponent of -1 (a-1) This is just another way to write 1/a1 , or more commonly, just 1/a.
"Please Excuse My Dear Aunt Sally" Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. You do things in Parentheses first, followed by exponents, then multiplication and so on.
There is only one law for exponents in division, and that is 1/ax = a-x
If the base is the same, you can subtract the exponents. For example (using "^" por powers):10^5 / 10^2 = 10^310^5 / 10^(-4) = 10^9
