a) 38 : 34 = 38 – 4 = 34 = 3.3.3.3 = 81;
b) 108 : 102 = 108 – 2 = 106 = 1000000
c) a6 : a = a6 – 1 = a5
a, \(3^8\) : \(3^4\) = \(3^{8-4}\) = \(3^4\)
b, \(10^8\) : \(10^2\) = \(10^{8-2}\) = \(10^6\)
c, \(a^6\) : a ( a \(\ne\) 0 ) = \(a^{6-1}\) = \(a^5\)
Tk mk nha
a) \(3^8:3^4=3^{8-4}=3^4=81\)
b) \(10^8:10^2=10^{8-2}=10^6=1000000\)
c) \(a^6:a=a^{6-1}=a^5\)
Chúc bạn học tốt!
Thân!
