Bună,
[tex] {81}^{5} \div {3}^{19} \times {3}^{2} - {3}^{2} + {27}^{2} \times {3}^{27} \div 84 ^{6} + {9}^{3} = \\ 3 ^{60} \div {3}^{19} \times {3}^{2} - 9 + 3 ^{6} \times 3 ^{27} \div {3}^{24} \div 3 ^{6} = \\ {3}^{43} - 3 + {3}^{3} = \\ 3 ^{43} - 9 + 27 = \\ 3 ^{43} + 18[/tex]
Sper că te-am ajutat
