The value of the given expression is 2. The correct option is C.2

<h3>Simplifying an Expression </h3>

From the question, we are to determine the value of the given expression

The given expression is

(8^2/3)^1/2

This can be properly written as

(8^{2/3})^{1/2}

First, clear the bracket by multiplying the powers

That is,
8^{\frac{2}{3}\times \frac{1}{2}  }

Simplifying, we get

8^{\frac{1}{3} }

This becomes

\sqrt[3]{8}

= 2

Hence, the value of the expression is 2. The correct option is C.2

Consider the system of equations.
anzhelika [568]

Answer: You can multiply the top equation by -1 to eliminate the x variable.

And the solution is (2,4/3)  in case you need it.

Step-by-step explanation:

2x + 3y = 8

2x + 6y = 12

If you multiply the upper equation or down equation by one, you will be able to eliminate the x variable.

-1( 2x + 3y) = -1(8)     New equation:   -2x -3y  = -8.

Add the new equation you got  by multiplying the top equation by -1 to the bottom equation.

Add them:     -2x -3y = -8

                      2x + 6y = 12  

                               3y = 4  

                              y = 4/3

You can now input the value for y into the one of the equations and solve for x.

-2x - 3(4/3) = -8

-2x -4 = -8  

     +4     +4

-2x = -4

x = 2

Use the discriminant to describe the roots of each equation. Then select the best description. 3x2 - 10 = 0. A) Double root B) R
Mademuasel [1]

1. discriminant = b^2 - 4ac = (-5)^2 - (4 x 1 x 7) = 25 - 28 = -3  [imaginary root]


2. discriminant = (-5)^2 - (4 x 1 x -4) = 25 - (-16) = 25 + 16 = 41  [real and irrational root]


3. discriminant = (8)^2 - (4 x 16 x 1) = 64 - 64 = 0    [double root]

In a village the number number of houses and flats are in a a ration 9:5
ki77a [65]

Answer:

180 houses

Step-by-step explanation:

The 3 part of the ratio 10 : 3 represents 30 bungalows, thus

30 ÷ 3 = 10 ← value of 1 part of the ratio

10 parts = 10 × 10 = 100 ← number of flats

The 5 part of the ratio 9 : 5 represents 100 flats, thus

100 ÷ 5 = 20 ← value of 1 part of the ratio, then

9 parts = 9 × 20 = 180 ← number of houses
