Question

Alguem pode me ajudar nesse problema de expoente fracionario?
81$\frac{1}{2}$ - 8$\frac{1}{3}$ + 32$\frac{1}{4}$ x 2

Answer 1

${81}^{\frac{1}{2}}-{8}^{\frac{1}{3}}+{32}^{\frac{1}{4}\times2}$

${({3}^{4})}^{\frac{1}{2}}-{({2}^{3})}^{\frac{1}{3}}+{({2}^{5})}^{\frac{1}{2}}$

$9-2+{2}^{\frac{5}{2}}=7+{2}^{\frac{5}{2}}$
