Learn how to find the value of Log and Antilog in easy method.
Log1=0.00
Log2=0.30
Log3=0.48
Log4=0.60
Log5=0.70
Log6=0.78
Log7=0.84
Log8=0.90
Log9=0.95
Log10=1.00

Tricks
*Log6=log(2×3)
=Log2+Log3
=0.30+0.48
=0.78

*Log8=Log2^3
=3Log2
=3×0.30
=0.90

*Log4.62
Solution:
Log4=0.60
Log5=0.70
Diff=0.10×0.62
=  0.062
Log4.62 =  0.60+0.062=0.662

*Log6.7
Solution:
Log6=0.78
Log7=0.84
Diff=0.06×0.7
= 0.042
Log6.7 =0.78+0.042
Antilog

*Antilog 2.72=10²·⁷²
Log5=0.70
(mid value of 5 and 6)5.5                        0.74(mid value of 0.70and 0.78)
Log6=0.78
=5.25 *10²(write first digit as power of 10)
*Antilog5.40
Log2=0.30
(mid value of 2 and 3)5.5                        0.39(mid value of 0.30and 0.48)
Log3=0.48
=2.55*10⁵(write first digit as power of 10)

*Antilog2 .64
Log4=0.60
(mid value of 4 and 5)4.5                        0.65(mid value of 0.60and 0.70)
Log5=0.70
=4.4*10⁻²
(write first digit as power of 10)
