a)3^4 *(3^2)^2= 3^4*3^4= 3^8
b)4^5 * 8^3= (2^2)^5 * (2^3)^3= 2^10*2^9=2^19
c)8^3/ 2^5= (2^3)^3/ 2^5= 2^6/ 2^5=2^1=2
d)125^7 / 25^10= (5^3)^7 / (5^2)^10= 5^21 / 5^20= 5^1=5
e)(1/9)^4 / (1/3)^3= (1/3^2 )^4 /(1/3)^3= (1/3)^8/ (1/3)^3=(1/3)^5
f)(0,5)^9/ (o,25)^4=(0,5)^9 / (0,5^2)^4= (0,5)^9/ (0,5)^8=(0,5) ^1= 0,5
g)(0,1)^9 / (0,001)^2= (0,1)^9 / (0,1^3)^2= (0,1)^9/ (0,1)^6= (0,1)^3
