2x² + 5x = -2
or, 2x²+5x+2=0
or,2x²+4x+x+2=0
or,2x(x+2)+1(x+2)=0
or,(x+2)(2x+2)=0

Two values can be found:
(x+2)=0                                  (2x+1)=0
or,x= - 2                               or,2x= -1
                                            or, x= -1/2

Use the given data to find the minimum sample size required to estimate a population proportion or percentage. margin of​ error:
guapka [62]
Minimum required sample size for a desired margin of error and confidence level when it is a proportion problem: n = (z2÷margin of error2)*p-hat*q-hat

The maximum value of p-hat*q-hat occurs where p-hat = .5 (found by taking the derivative of (p-hat)*(1-p-hat) and setting it equal to 0 to find the maximum. n = ( 2.5762( for 99% confidence interval)÷.0482 )*.5*.5 = 720.028 or 721

Which is equivalent to <img src="https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B9%7D%20%5E%7B%5Cfrac%7B1%7D%7B2%7Dx%20%7D" id="TexForm
Digiron [165]

For this case we have that by definition of properties of powers and roots, it is fulfilled that:

\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}

So:

\sqrt [4] {9 ^ {\frac {1} {2} x}} = 9 ^ {\frac {\frac {1} {2}} {4} x} = 9 ^ {\frac {1} {8} x}

So, we have to:

\sqrt [4] {9 ^ {\frac {1} {2} x}} = 9 ^ {\frac {1} {8} x}

Answer:

9 ^ {\frac {1} {8} x}

Option B
