Define the value of the expression 3^2 x 3^{-5}
Tanya [424]

Answer:

Between 0 and 1

Step-by-step explanation:

The given expresion is

{3}^{2} \times  {3}^{ - 5}

Recall that:

{a}^{m}  \times  {a}^{n}  =  {a}^{m + n}

We apply this property of exponents to get;

{3}^{2}  \times  {3}^{ - 5}  =  {3}^{2 +  - 5}  =  {3}^{ - 3}

We rewrite to obtain a positive index as:

{3}^{2}  \times  {3}^{ - 5}  =  \frac{1}{ {3}^{3} }  =  \frac{1}{27}

Therefore the value of the expression is between 0 and 1.

Question 2 of 10
AnnyKZ [126]

The length of AB will be 10 units. Option B is corect. The formula for the distance between the two points is applied in a given problem.

<h3>What is the distance between the two points?</h3>

The length of the line segment connecting two places is the distance between them.

The distance between two places is always positive, and equal-length segments are referred to as congruent segments.

The given coordinate in the problem is;

(x₁,y₁)=(-2,-4)

(x₂, y₂)= (-8, 4)

The distance between the two points is found as;

\rm d= \sqrt{(-8-(-2))^2+(4-(-4))^2}\\\\ d=10 \ units

Hence, option B is corect.

To learn more about the distance between the two points, refer to;
