Change the following from logarithmic form to exponential form :
1) log 464 = 3
2) log162 = 1/4
3) log5(1/25) = -2
4) log100.1 = -1
5) log6216 = 3
6) log93 = 1/2
7) log51 = 0
8) log√3 9 = 4
9) log64 (1/8) = -1/2
10) log0.5 8 = -3
Solve for x :
11) log2x = 1/2
12) log1/5x = 3
Answers :
1) 64 = 43
2) = 161/4
3) (1/25) = 5-2
4) 0.1 = 10-1
5) 216 = 63
6) 3 = 9(1/2)
7) 1 = 50
8) 9 = (√3)4
9) (1/8) = 64(-1/2)
10) 8 = 0.5-3
11)
log2x = 1/2
Convert to exponential form.
x = 21/2
x = √2
12)
log1/5x = 3
Convert to exponential form.
x = (1/5)3
x = 13/53
x = 1/125
