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^6-1 = a^5
a)
\(3^8:3^4=3^{8-4}=3^4\)
b)
\(10^8:10^2=10^{8-2}=10^6\)
c)
\(a^6:a=a^{6-1}=a^5\)
a, =\(3^{\left(8-4\right)}=3^4=81\)
b, \(=10^{8-2}=10^6=1000000\)
c, \(=a^{\left(6-1\right)}=a^5\)
a) 38 : 34 = 38 – 4 = 34
b) 108 : 102 = 108 – 2 = 106
c) a6 : a = a6 – 1 = a5
38 : 34 = 38-4 = 34
108 : 102 = 108-2 = 106
a6 : a = a6-1 = a5
a)38:34=38-4=34 b)108:102=108-2=106 c)a6:a=a6-1=a5
\(a,\) \(3^8:3^4=3^{8-4}=3^4=81\)
\(b,\) \(10^8:10^2=10^{8-2}=10^6=1000000\)
\(c,\) \(a^6:a=a^{6-1}=a^5\)
Chúc bạn học tốt !
a) 38 : 34 = 38 - 4 = 34
b) 108 : 102 = 108 - 2 = 106
c) a6 : a = a6 : a1 = a6 - 1 = a5
