Which is equivalent to

the answer is the one on the bottom

Step-by-step explanation:

I know you have choices so I'm hoping this is one of them.

The way you write the problem is really important for us to help you. I'm still not quite sure about where the x is in the problem. I'm thinking it is multiplied at the end. S here goes.

- sqrt (10) ^ (3/4) x

sqrt 10 is the same as 10 ^ (1/2)

- (10)^(1/2)^(3/4) x

multiply (1/2) and (3/4)

-(10)^(3/8) x

- eighth root(10^3) x

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
