soal

x=  27  dan y= 9

. .

sf (xy)^{frac{4}{5}} = (27. 9){frac{4}{5}} = (3^3. 3^2)^{frac{4}{5}} = (3^5)^{frac{4}{5}}= 3^4 = 81

x^{frac{1}{3}} + y^{frac{1}{2}} =27^{frac{1}{3}} + 9^{frac{1}{2}} = (3^3)^{frac{1}{3}} + (3^2)^{frac{1}{2}} = 3 + 3= 6

sf (x+y)^{frac{3}{2}} =(27+9)^{frac{3}{2}} =(36)^{frac{3}{2}}= (6^2)^{frac{3}{2}}=6^3= 216

catatan : (a^m)^n/m = a^n

Penjelasan dengan langkah-langkah:

a. (27 . 9)^4/5 = (3³. 3²)^4/5

= (3^5)^4/5

= 3⁴ = 81

b. (3³)^⅓ + (3²)^½ = 3 + 3 = 6

c. ( 27 + 9)^3/2 = 36^3/2

= (6²)^3/2

= 6³ = 216
