Explicație pas cu pas:
a)
[tex]2 {}^{2} + {3}^{2} - {2}^{3} = \\ = 4 + 9 - 8 = \\ = 13 - 8 = \\ = 5[/tex]
b)
[tex] {4}^{3} + {2}^{4} - {4}^{2} = \\ = 64 + 16 - 16 = \\ = 64[/tex]
c)
[tex] {5}^{2} \div 5 = {5}^{2} \div {5}^{1} = 5 {}^{2 - 1} = 5 \\ sau \: {5}^{2} \div 5 = 25 \div 5 = 5[/tex]
d)
[tex] {5}^{3} \times {5}^{1} \div {5}^{4} = {5}^{3 + 1 - 4} = {5}^{0} = 1[/tex]
e)
[tex](2 {}^{3} ) {}^{2} \times (2 {}^{2} ) {}^{3} = 2 {}^{3 \times 2} \times {2}^{2 \times 3} = \\ = {2}^{6} \times {2}^{6} = 2 {}^{6 + 6} = {2}^{12} [/tex]
