Question: generate 5 radical problems
1. Simplify the expression $$\sqrt{50}$$.
2. Solve for $x$: $$\sqrt{x+5} = 7$$.
3. Simplify $$\frac{\sqrt{18}}{\sqrt{2}}$$.
4. Rationalize the denominator: $$\frac{5}{\sqrt{3}}$$.
5. Solve for $x$: $$\sqrt{2x+3} + 1 = 4$$.
Each problem involves working with square roots and radicals, including simplification, solving equations, and rationalizing denominators.
