Dau 15 pumcte

Answer 1

${2}^{5} : {4}^{2} + {3}^{9} : {9}^{3} : {3}^{3} = {2}^{5} \times {2}^{4} + {3}^{9} : {3}^{6} : {3}^{3} = {2}^{5 - 4} + {3}^{9 - 6 - 3} = {2}^{1} + {3}^{0} = 2 + 1 = 3$

Answer 2

2⁵ : 4² + 3⁹ : 9³ : 3³ = 3

= 2⁵ : ( 2² ) ² + 3⁹ : ( 3² ) ³ : 3³ =

= 2⁵ : 2⁴ + 3⁹ : 3⁶ : 3³ =

= 2 ⁽ ⁵ ⁻ ⁴ ⁾  + 3 ⁽⁹⁻ ⁶⁻ ³ ⁾ =

= 2¹ + 3⁰ =

= 2 + 1 =

= 3
