Question

Without consulting the log table the value of log 50 base 10+log 2 base 10 - 2 can be found as equal to :

Answer 1

log 2 ti the base 10 +log 50 to the base 10 gives log 100 to the base 10
As log100 to the base 10 is 2
then 2-2=0

Answer 2

Answer:

0

Step-by-step explanation:

The given expression is

$log_{10}50+log_{10}2-2$

We need to find the value of given expression without consulting the log table.

Using the product property of log, the given expression can be written as

$log_{10}(50\times 2)-2$             $[\because log_am+log_an=log_amn]$

$log_{10}(100)-2$

$log_{10}(10^2)-2$

Using property of logarithm, we get

$2-2$                       $[\because log_aa^x=x]$

$0$

Therefore, the value of given expression is 0.
