Answer:

Terms

Step-by-step explanation:

Hello!

The expression 2x +5 has two different terms: 2x and 5

<h3><u>Terms:</u></h3>

Terms are values in an expression that are different from each other. They are values with different coefficients.

For example:

2x has a coefficient of 2, because 2x = 2(x)
5 has a coefficient of 1 because 5 = 1(5)

<h3><u>Like Terms:</u></h3>

Like terms are values with the same factors or coefficients.

Let's use an example equation: 2x + 5 + 7x - 9

2x and 7x are like terms, because they have a factor of x, which simplifies to 2x + 7x = 9x
5 and -9 have the same factor of -1, so if we simplify: 5 + (-9) = 5 - 9 = -4
Combining the two terms we have 9x - 4

B. Does a12 x a4 = a8 x a8 for all values of a? Explain.

Answer:

We can use the Laws of Exponent to rewrite both sides of the equation:

Let a¹² x a⁴ = a⁸ x a⁸

⇒ a¹²⁺⁴ = a⁸⁺⁸

a¹⁶ = a¹⁶ ✅

⇒ a¹² x a⁴ = a⁸ x a⁸ is true for all values of a.

Explanation:

The equation a¹² x a⁴ = a⁸ x a⁸ is true because, on both the RHS and LHS of the equation, both terms in 'a' have exponents that when added (Law of Multiplication of Exponents) are equal to each other, i.e. 12+4 = 8 + 8.
