Question

(3^2)^5 - 3^7/(3^5)^3

---

Answer 1

( 3² )^5 - 3^7 / ( 3^5 )³ = 26/6 561.

1) ( 3² )^5 = 59 049;

3² = 3 × 3 = 9;

9^5 = 9 × 9 × 9 × 9 × 9 = 59 049;

2) 3^7 = 3 × 3 × 3 × 3 × 3 × 3 × 3 = 2 187;

3) 59 049 - 2 187 = 56 862;

4) ( 3^5 )³ = 14 348 907;

3^5 = 3 × 3 × 3 × 3 × 3 = 243;

243³ = 243 × 243 × 243 = 14 348 907;

5) 56 862/14 348 907 = 26/6 561.
