Calcule

A)3⁴÷²=
B)2¹²÷4=
C)5⁸÷⁴=
D)27²÷3=
E)25⁵÷2=
F)4.096³÷4=

Answer 1

A)3⁴÷²=        $3^{4:2} = 3^{2} = 9$              B)2¹²÷4=  $2^{12} : 2^{2} = 2^{12-2} = 2^{10} = 1024$

C)5⁸÷⁴=     $5^{8:4} = 5^{2} = 25$              D)27²÷3=   $9^{2} = 81$

E) $25^{5:2} = 25^{2,5} = 25^{\frac{5}{2} } = \sqrt[2]{25^{5} } = \sqrt[2]{25^{2}.25^{2}.25^{1} } = 25.25\sqrt[2]{25} = 25.25.5 = 3125$         F) 4.096³÷4 = 4,096³ ÷ 4 = 1,024³ = 1,0737
