$\sqrt{8u+1}+9=0$

Short answer

The solution is$10$

Step-by-step solution

Step 1. Given information

The given expression is$\sqrt{8u+1}+9=0$

Step 2. Squaring on both sides 

$$\begin{gathered} \sqrt{8u+1}+9=0 \\ \sqrt{8u+1}=-9 \\ Squaringonbothsides \\ {\left(\sqrt{8u+1}\right)}^2=81 \\ 8u+1=81 \\ u=10 \end{gathered}$$

The solution is$10$

Step 3. The solution 

The solution is$10$
