Здравствуйте, Terentjeva Elena!
1) log64 x= -1/3
x = 64^(-1/3) = 1/64^(1/3) = 1/4
2) log0,2 x=4
x = 0,2^4 = 0,0016
3) log0,32 x= -1
x = 0,32^(-1) = 3,125
4) log4/7 x= -2
x = (4/7)^(-2) = 49/16
5) log6 x=1/4
x = 6^(1/4)
6) log0,0016 x= -4
x = 0,0016^(-4) = 152587890625
7) lgx=3
x = 10^3 = 1000
8) lgx= -2
x = 10^(-2) = 0,01
9) lgx= 1/3
x = 10^(1/3)
10) log4 1/16 = -2
11) log2 16 = 4
12) log3 27 = 3
13) log1/5 125 = -3
14) logx 0,008 = 3
x = 0,008^(1/3) = 0,2
15) logx 1000 = 3
x = 1000^(1/3) = 10
16) logx 50 = 3/2
x = 50^(2/3)
