Answer:

$\boxed{\sf Associative \:property\: of \:addition}$

$\sf (4 + 5) + 2 = 4 + (5 + 2)$

$\boxed{\sf Distributive \:property}$

$\sf 2(2x + 4) = 4x + 8$

$\boxed{\sf Associative\: property \:of \: multiplication}$

$\sf ( 7 * x ) *3 = 7 (x *3)$

$\boxed{\sf Commutative \:property\: of \:multiplication}$

$\sf ( 8* x *2) = (x *8* 2)$

$\boxed{\sf Commutative \:property \:of \: addition}$

$\sf ( 7 + 3) + 1 = 1 + (7 + 3)$

________________________________

Associative property of addition: Changing grouping of addends doesn't change the sum.

Distributive property: Multiplying a sum by a number is the same as multiplying each addend by that number and then adding the two products.

Associative property of multiplication: Changing grouping of the factors doesn't change the products.

Commutative property of multiplication: Changing order of the factors doesn't change the products.

Commutative property of addition: Changing order of addends doesn't change the sum.

Answer:

See explanation below for further details.

Step-by-step explanation:

A rational consist of two real numbers such that:

$\frac{a}{b} =c$

If c is a polynomial with a certain grade, then, both the numerator and the denominator must be also polynomials and the grade of the numerator must be greater than denominator.

If c is linear function, that is, a first order polynomial, then a must be a (n+1)-th polynomial and b must be a n-th polynomial.

Example:

If $a = x^{2}$ and $b = x$ , then:

$c = \frac{x^{2}}{x}$

$c = x$

If c is a quadratic function, that is, a second order polynomial, then a must be a (n+1)-th polynomial and b must be a n-th polynomial.

Example

If $a = 3\cdot x^{3}$ and $b = x$ , then:

$c = \frac{3\cdot x^{3}}{x}$

$c = 3\cdot x^{2}$

But if c is an exponential, both the numerator and the denominator must be therefore exponential function and grade of each exponential function must different to the other.

Example

If $a = 10^{2x}$ and $b = 3\cdot 10^x$ , then:
