1. √9√3= 3√√3 = 3⁴√3 ~~ 3,94822
2. 3 2/3 * ⁵√9² = ∛3² - ⁵√81 = ∛9 - ⁵√81 ~~ -0,328141
3. 6⁵ * 5⁴/30⁴ = 6⁵ * 5⁴/5⁴ * 6⁴ = 6⁵/6⁴ = 6
4. 3²⁶ + 3²⁵/ 3²⁵ + 3²⁴ = (3+1) * 3²⁵/ (3+1) 3²⁴= 4*3/4 = 3
5. 7² * 49/ ∛7 = 7⁴/∛7 = 7⁴/∛7 * ∛7²/∛7 = 7⁴ * ∛7²/ ∛7³ = 7⁴ * ∛7²/ 7 = 343 * ∛49 = 349∛49
6. 4⁴⁸ + 4⁴⁸ + 4⁴⁸+ 4⁴⁸= 4 * 4⁴⁸ = 4⁴⁹
7. 32⁻³ / (1/8)⁵ = 2⁻¹⁵ / 2⁻¹⁵ = 1
