Given :-
- log (145/8) - 3log (3/2) + log (54/29)
Explanation
We know some important formula
★ log (x/y) = log x - log y .
★ log x ^n = n log x.
★ log xy = log x + log y .
So, Now calculate
= log (145/8) - 3log (3/2) + log (54/29)
Use Formula
( log (x/y) = log x - log y .)
= log 145 - log 8 - 3 (log 3 - log 2) + log 54 - log 29
Use Formula
( log x^n = n log x )
= log (5 × 29) - log 8 - log 3³ + log 2³ + log (27 × 2) - log 29
Use Formula
( log xy = log x + log y )
= log 5 + log 29 - log 8 - log 27 + log 8 + log 27 + log 2 - log 29
Here,
( log 29 , log 27 & log 8 are cancel )
= log 5 + log 2 .
Value of log 5 & log 2 by log table .
★ log 2 = 0.3010
★log 5 = 0.6989
Keep above value,
= 0.6989 + 0.3010
= 0. 9999 [ Ans.]
