B. [tex]\sqrt{5 -\frac{20}{9}}[/tex] × 3 = [tex]\sqrt{\frac{25}{5} -\frac{20}{9}}[/tex] × 3 = [tex]\sqrt{\frac{225}{45} -\frac{100}{45}}[/tex] × 3 = [tex]\sqrt{\frac{125}{45}}[/tex] × 3 = [tex]\sqrt{\frac{25}{9}}[/tex] × 3 = [tex]\frac{5}{3}[/tex] × 3 = 5
C. [tex]\sqrt[3]{5^{2} + 2}[/tex] = [tex]\sqrt[3]{25 + 2}[/tex] = [tex]\sqrt[3]{27}[/tex] = 3
E. [tex]\sqrt[3]{\frac{5^{2}}{2}4 - 23}[/tex] = [tex]\sqrt[3]{\frac{25}{2}4 - 23}[/tex] = [tex]\sqrt[3]{\frac{100}{2} - 23}[/tex] = [tex]\sqrt[3]{50 - 23}[/tex] = [tex]\sqrt[3]{27}[/tex] = 3
