Which of the following steps correctly leads to the simplest form of the expression: √50 + √32 − 3√2?
29
Combine all terms directly: √50 + √32 − 3√2 = √84
Simplify each radical first: 5√2 + 4√2 − 3√2 = 6√2
Factor out common radicals after simplification: 9√2 − 3√2 = 6√2
No simplification is needed: √50 + √32 − 3√2 is already in its simplest form.

Which of the following options correctly applies the rules of exponents?
$c^{\frac{1}{3}}+\ c^{\frac{1}{4}}=c^{\frac{1}{7\ }}$
$3^{\frac{1}{4}+\frac{1}{6}}=3^{\frac{5}{12}}$
$c^{\frac{2}{5}}=\sqrt[5]{c^2}$
$\left(c^{\frac{3}{4}}\right)^{\frac{2}{3}}\ =\ c^{\frac{1}{2}}$
