a)
3⁵/9² - 2³/4⁻¹ + 2/25⁻¹⁾² = 3⁵/(3²)² - 2³/(2²)⁻¹ + 2 * √25 =
= 3⁵/3⁴ - 2³/2⁻² + 2 * 5 = 3⁵⁻⁴ - 2³⁻⁽⁻²⁾ + 10 = 3¹ - 2³⁺² + 10 =
= 3 - 2⁵+ 10 = 3 - 32+ 10 = - 32 + 13 = - 19
b)
16⁻¹⁾⁴/5⁻² - 8²⁾³/27⁻¹⁾³*²⁾³ = (1/16)¹⁾⁴ : (1/5)² - (2³)²⁾³ : 27⁻²⁾⁹ =
= ⁴√(1/16) : 1/25 - 2² : (1/27)²⁾⁹ = 1/2 : 1/25 - 4 : [(1/3)³]²⁾⁹ =
= 1/2 * 25 - 4 : 1/3²⁾³ = 25/2 - 4 : ∛(1/3)² =25/2 - 4 : 1/∛9 =
= 12,5 - 4 * ∛9 = 12,5 - 4∛9
