Question

The value of log_10 125 + log_10 8 = X, then X =

Answer 1

Answer:x =3

Step-by-step explanation:

$log_{10}{125} +  log_{10}(8) = x$

when base is same of log , arguments can be multiplied if log are in addition

⇒ $log_{10}(125*8) = log_{10} (1000) = log_{10} (10^3)  = 3log_{10}(10)$

since when base and arguments are same thne log equals to 1

thus we have  3 = x

or  x = 3  Ans.

Answer 2

Answer:

3

explanation:-

log10^125+log10^8

log10^125*8=log10^1000=X

1000=10^X

10^3=10^X

bases are equal

hence X=3
