Question

Evaluate √24-x when x=6 Write the answer as a decimal. Round to the nearest hundredth if necessary.

Answer 1

If the x is also supposed to be included in the radical, then you should be $\sqrt{18}$ which simplifies to $3\sqrt{2}$ or approximately 4.24

If the x is on the outside, $\sqrt{24}$ simplifies to $2\sqrt{6}$. Now do $2 \sqrt{6} - 6$ in a calculator to get approximately - 1.10
