Simplify \root(3)(8x^(6))y^(12)

ExtremeBDS [4]

The simplification form of the provided expression is 2x²y⁴ option first is correct.

<h3>What is an expression?</h3>

It is defined as the combination of constants and variables with mathematical operators.

We have an expression:

$= \rm \sqrt[3]{8x^6y^{12}}$

$\rm =\sqrt[3]{8}\sqrt[3]{x^6}\sqrt[3]{y^{12}}$

$\rm \rm = \rm 2\sqrt[3]{x^6}\sqrt[3]{y^{12}}$

$\rm =2x^2\sqrt[3]{y^{12}}$

$\rm =2x^2y^4$

Thus, the simplification form of the provided expression is 2x²y⁴ option first is correct.

The weight W of an object varies inversely as the square of the distance d from the center of the earth. At sea level (3978 mi

eimsori [14]

$\bf \begin{array}{llllll}
\textit{something}&&\textit{varies inversely to}&\textit{something else}\\ \quad \\
\textit{something}&=&\cfrac{{{\textit{some value}}}}{}&\cfrac{}{\textit{something else}}\\ \quad \\
y&=&\cfrac{{{\textit{k}}}}{}&\cfrac{}{x}
\\
&&y=\cfrac{{{ k}}}{x}
\end{array}$

with "k" being the "constant of variation"

so. hmm in this case is "w" inversely varying to the square of the distance or d²

thus $\bf w=\cfrac{k}{d^2}\qquad 
\begin{cases}
d=3978\\
w=129
\end{cases}\implies 129=\cfrac{k}{3978^2}$

solve for "k", to see what the constant of variation is

and plug it back in $\bf w=\cfrac{k}{d^2}$

now.. .to find her weight when she's 144miles above the surface, well
that's just $\bf w=\cfrac{k}{(3978+144)^2}$

and since you already know what "k" is, just divide and simplify away, to get "w"
