  24^(1/3) + 192^(1/5) = 8^(1/3)*3^(1/3) + 32^(1/5)*6^(1/5) = 2*3^(1/3) + 2*6^(1/5) if you need an approximation, use your calculator.

  (24)1/3 =81/3*31/3 =2*31/3 You can do the same for 1921/5 and find common factors, if any. If you need a numerical answer, your calculator is your best tool. (ans.≅5.7464...)
