Explicație pas cu pas:
1. a) 2³ * 2⁵ = 2⁸
b) [tex]2^{80} : 2^{78} =\\= 2^{2} = 4\\[/tex]
c) 5² + 3²=
= 25 + 9 =
= 34
d) (2⁵)³ : (2²)⁷=
= [tex]2^{15} : 2^{14}[/tex]=
= 2
e) [tex](4 + 4^{192} : 4^{188} ) : 5=\\= (4 + 4^{4} ) : 5 =\\= (4 + 256) : 5 =\\= 260 : 5 =\\= 52\\[/tex]
2) a) 2[tex]2^{15} \leq 3^{10} \\(2^{3} )^{5} = 8^{5} \\(3^{2} )^{5} = 9^{5}[/tex]
b) [tex]9^{15} = 27^{10} \\(3^{2} )^{15} = 3^{30} \\(3^{3} )^{10} = 3^{30}[/tex]
