Undefinable terms are terms with no formal definitions. Formal definitions are obtained when specific words are used to define a term. In mathematics, specifically, Geometry words like line, point, and plane have no definite definition, So descriptions are used to identify them.

For example, in describing a point, we note that a point has no dimensions, it is usually denoted with a capital letter, and it indicates a position. Also in a coordinate plane, it is denoted with descriptions such as (u,v). Corresponding descriptions are given of other undefinable terms.

3^x ( x^2 -3) i don't know how to solve this problem

geniusboy [140]

3ˣ (x² - 3)

Basically, just multiply everything together.

Step 1 : 3x × x² = 3x³ because when multiplying exponents, all you're really doing is adding them on top. So, x + 2x = 3x! But, they are exponents, so you get 3x³.

Step 2 : 3x ˣ × (-3) = -9ˣ

Now, our new question is : 3x³ - 9x

You wouldn't simplify this because x³ is NOT the same as x.

~Hope I helped!~
