a, \(3^{15}:3^5=3^{15-5}=3^{10}\)
b, \(4^6:4^6=4^{6-6}=4^0\)
c, \(9^8:32=\left(3^2\right)^8:2^5=3^{16}:2^5\)
a)
\(3^{15}:3^5=3^{15-5}=3^{10}\)
b)
\(4^6:4^6=1\)
c)
\(9^8:3^2=\left(3^2\right)^8:3^2=3^{16}:3^2=3^{16-2}=3^{14}\)
a) 315 : 35 = 315 - 5 = 310
b) 46 : 46 = 46 - 6= 40 = 1
c) 98 : 32 = ( 32 )4 : 32 = 316 : 32 = 314
