QuestionSolve the following equation for $u$. $$\begin{array}{l} 8=a \sqrt{u} \\ u=\square \end{array}$$

Studdy Solution
To solve for $u$, square both sides of the equation to eliminate the square root:
$$\left(\frac{8}{a}\right)^2 = (\sqrt{u})^2$$ $$\frac{64}{a^2} = u$$
The value of $u$ is:
$$u = \frac{64}{a^2}$$
