a)1,5^8 * (2/3)^8 = (3/2 * 2/3)^8 = 1^8 = 1
b)0,6^5 * (6 2/3)^5 = (6/10 *20/3)^5 = 4^5 =1024
c)10000 * 0,2^4 = 10^4 * 0,2 ^4 = (10*0,2)^4 = 2^4 = 16
d)0,8^5 * 2,5^5=(0,8*2,5)^5=2^5=32
e)(5/7)^3/(2 1/7)^3=(5/7 : 15/7)^3=(5/7*7/15)^3=(1/3)^3=1/27
f)81 * 0,25^4 : 0,75^4 = 3^4 * 0,25^4 : 0,75^4 = (3*1/4*4/3)^4=1^4=1
