216 = 6^3
256 = 4^4
243 = 3^5

Hence, 216^-(2/3) = 6^3^(-2/3) = 6^-2
Similarly, 256^-3/4 = 4^-3
243^-1/5 = 3^-1

3/6^-2 + 2/4^-3 + 2/3^-1 = 3*6^2 + 2*4^3 + 2*3 = 108 + 128 + 6 = 242
Hope this helps

Answer:

Step-by-step explanation:

216 = 6^3

256 = 4^4

243 = 3^5

Hence, 216^-(2/3) = 6^3^(-2/3) = 6^-2

Similarly, 256^-3/4 = 4^-3

243^-1/5 = 3^-1

3/6^-2 + 2/4^-3 + 2/3^-1 = 3*6^2 + 2*4^3 + 2*3 = 108 + 128 + 6 = 242

Hope this help
