1 thought on “express each of the following rational number in power nation -216/343<br />do it second method​”

1. Step-by-step explanation:

   take out the factors first

   216 = 2×2×2×3×3×3

   343 = 7×7×7

   now , 216 can be written as 2^3 × 3^3

   and 343 as 7^3

   so ans is -(2^3 × 3^3) ÷ (7^3) = – (6^3) / (7^3)
