How do you express a product of variables using exponents?

Back

You can express repeated multiplication of the same variable using exponents. For example, 2.1 • x • z • z • z • z • z can be written as 2.1xz^5.

How do you evaluate an expression with given values for variables?

Back

To evaluate an expression, substitute the values of the variables into the expression and perform the arithmetic operations. For example, for a + b • 2 with a = 3 and b = 2, the evaluation is 3 + 2 • 2 = 7.

What is the difference between a term and a factor in algebra?

Back

A term is a single part of an expression, while a factor is a number or variable that is multiplied in a term. For example, in the term 5x, 5 is a coefficient and x is a variable.

How do you combine like terms?

Back

To combine like terms, add or subtract their coefficients while keeping the variable part the same. For example, 3x + 5x = 8x.
