a) 3.5.15.9 = 3.5.5.3.3.3 = 34.52
b) 10.100.1000 = 10.10.10.10.10.10 = 106
c) 2.x.2.x.2.x = 23.x3
d) a3.a6.a9 = a3+6+9 = a18
e) x2.x.x5.x7.x8 = x2+1+5+7+8 = x23
f) 34.44 = (3.4)4 = 124
g) 23.84 = 23 . (23)4 = 23.212 = 215
a: \(=15^2\cdot3^2=45^2\)
b: \(=10\cdot10^2\cdot10^3=10^6\)
c: \(=\left(2x\right)^3=8x^3\)
b: \(=a^{3+6+9}=a^{18}\)
d: \(=x^{2+1+5+7+8}=x^{23}\)
