Question

Solve for x to the nearest 10th ; x^3/4=129


Please help !

Answer 1

what do you think?

Answer 2

it's gonna be 8.0207 approx 8.0

Answer 3

first make x as the subject

x^3 = 129 * 4

Answer 4

hint:
we have to compute the (4/3)-th power of both sides, so we can write:
\[\Large \begin{gathered}
{\left( {{x^{3/4}}} \right)^{4/3}} = {129^{4/3}} \hfill \\
x = \sqrt[3]{{{{129}^4}}} = ...? \hfill \\
\end{gathered} \]
