Question

how many log of negative num. show a particular value?​

Answer 1

Log of negative numbers is not defined.

For antilog of negative numbers write the number x as [x] + {x}.

[x] will give you the exponent to tha base 10 and antilog of {x} found using antilog table will give you coefficient.

For example

antilog (-0.699)

= antilog (-1+0.301)

= 2x 10^(-1)

(As log 2 = 0.301, antilog (0.301)= 2)

Answer 2

if base index(e) is of opposite side of 1 give negative value
