Beyond the Answer
Mari kita hitung satu per satu. Pertama, kita hitung \( a^{\frac{5}{3}} \): \[ 8^{\frac{5}{3}} = (2^3)^{\frac{5}{3}} = 2^5 = 32 \] Selanjutnya, kita hitung \( b^{\frac{1}{2}} \): \[ 4^{\frac{1}{2}} = 2 \] Lalu, kita hitung \( c^{\frac{3}{2}} \): \[ 9^{\frac{3}{2}} = (3^2)^{\frac{3}{2}} = 3^3 = 27 \] Sekarang kita masukkan nilai-nilai tersebut ke dalam rumus: \[ a^{\frac{5}{3}} + b^{\frac{1}{2}} - c^{\frac{3}{2}} = 32 + 2 - 27 \] \[ = 34 - 27 = 7 \] Jadi, jawabannya adalah 7.
