In order to figure out how to find cube roots, you must review square roots. Finding the square root of a number means determining what other number needs to be multiplied by itself to get the original number. For example:

√81 = 9

Students at all levels of math need a list of perfect squares. Knowing the most common perfect squares makes it much easier to solve square roots, which show up in all kinds of math problems. But before we go into perfect squares, let's review the definition of square roots.

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power. In other words, none of the exponents can be greater than 1.

For example, *x²* is a variable raised to the second power, but *x* is a variable raised to the first power.

5 is an example of a constant.

Note that the coefficients in front of the variables don't matter. Let's take a couple of these polynomials (a polynomial just means an expression with two or more terms) as examples.

2x - y + 3 is a linear expression.

x + y + z⁵ is a non-linear expression. It contains a term raised to the fifth power.

4 - 2 is a linear expression.

The distributive property of multiplication is a property of real numbers that shows how we can break apart multiplication problems into separate terms. The property states that an algebraic expression *a(b + c*) becomes *ab + ac*. In other words, the multiplication of a distributes to both variables inside the parentheses, b and c.

Are repeating decimals rational? The answer is yes. But before we talk about why, let's review rational numbers. A rational number is a fraction in its lowest term. It's written in form a/b, where both *a* and *b* are integers, and *b* is a non-zero denominator.

Now, let’s talk about why repeating decimals are considered rational numbers.
