There is no way of knowing because they did not specify if it’s 17ft high, 17ft width, or 17ft length so she is most likely wrong

Which expression is equivalent to sqrt2x^5/18 ? Assume x>0.
qwelly [4]

Answer

\frac{x^{2} \sqrt{x} }{3}

Step-by-step explanation:

first off rt(2x^5) can be simplified as x^2 rt(2x) because we can break up x^5 into x^4 * x. x^4 is a perfect square so factor out a x^2.

the denominator \sqrt{18} can be written as 3\sqrt{2} since the factors of 18 involve a perfect square of 9. 9*2 is 18 so factor out a 3.

the whole fraction :

\frac{x^{2} \sqrt{2x} }{3\sqrt{2} }

cancel out the \sqrt{2} and you are left with \frac{x^{2} \sqrt{x} }{3}
