MATH 7 UNIT III PRE-UNIT ASSESSMENT

A constant is any symbol representing one fixed value.

A variable is any symbol representing possible values of a quantity.

A variable is any symbol representing possible values of a quantity.

In the expression $$\left(-3x\right)^5$$ , 5 is the exponent.

The expression $$\left(-6\right)^3$$ has an expanded notation equivalent to $$-6\times-6\times-6$$

Term is a number, a variable, or a product of numbers and variables.

Terms are part of an algebraic expression separated by an operational sign.

In any term, the coefficient is the product of the numerical and literal components.

Coefficients can be divided into two types: numerical coefficients and literal coefficients.

Numerical Coefficient: This is the constant number that multiplies the variable(s) in an expression. It represents the magnitude of the term without any variables attached.

Literal Coefficient: This refers to the variable(s) in a term. It includes any letters or symbols that represent quantities.

in the expression, $$4x^2$$ , $$4$$ is the numerical coefficient, and $$x^2$$ is the literal coefficient.

A Monomial is a polynomial of one term only while a Binomial is a polynomial of two terms.
