Which statements are true about the expression? Check all that apply.

The 6 without an exponent is equivalent to the 6 having a 0 exponent.

The sum of the exponents is 2.

Multiply the exponents to simplify the expression.

The expression has a value of -

An equivalent expression is 65.6-7

Answer:

Some of the Exponents = -2 that is true, not 2.

Step-by-step explanation:

Let's check one at a time.

(a)The 6 without an exponent is equivalent to the 6 having a 0 exponent.

[tex]6^{0} =1[/tex] and [tex]6^{1}[/tex] = 6 (no exponent. 6 [tex]\neq[/tex] 1 therefore this statement is False.

(b)The sum of the exponents is -2.

let's check , if the base is same we can add the exponents that is the exponent rule.(well established).

if we add exponents in the given expression we get.

[tex]6^{1} 6^{0} 6^{3} =6^{1+0+(-3)} =6^{-2}[/tex], therefore we can see that the sum of the exponents = -2 this is true.

(c) An equivalent expression is 65.6-7, lets evaluate our above expression, it is equal to [tex]\frac{1}{36}[/tex] which we can see that [tex]\frac{1}{36} \neq 65.6-7[/tex] ,therefore this statement is false as well.
