Answer:
D, B, C, A
Step-by-step explanation:
Solve the equations by combining like terms, isolating the variable, and dividing the equation by the coefficient of the variable.
Doing this, the first equation should be 2, the second equation should be -2, the third equation should be -1, and the last equation should be -6.
Then, we can order them.
The simplified expression of
is ![\frac{9}{x^9}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7Bx%5E9%7D)
<h3>How to simplify the expression?</h3>
The expression is given as:
![\sqrt{\frac{162x^9}{2x^{27}}}](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7B162x%5E9%7D%7B2x%5E%7B27%7D%7D%7D)
Divide 162 and 2 by 2
![\sqrt{\frac{81x^9}{x^{27}}}](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7B81x%5E9%7D%7Bx%5E%7B27%7D%7D%7D)
Take the square root of 81
![9\sqrt{\frac{x^9}{x^{27}}}](https://tex.z-dn.net/?f=9%5Csqrt%7B%5Cfrac%7Bx%5E9%7D%7Bx%5E%7B27%7D%7D%7D)
Apply the quotient rule of indices
![9\sqrt{\frac{1}{x^{27-9}}}](https://tex.z-dn.net/?f=9%5Csqrt%7B%5Cfrac%7B1%7D%7Bx%5E%7B27-9%7D%7D%7D)
Evaluate the difference
![9\sqrt{\frac{1}{x^{18}}}](https://tex.z-dn.net/?f=9%5Csqrt%7B%5Cfrac%7B1%7D%7Bx%5E%7B18%7D%7D%7D)
Take the square root of x^18
![\frac{9}{x^9}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7Bx%5E9%7D)
Hence, the simplified expression of
is ![\frac{9}{x^9}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7Bx%5E9%7D)
