Question

If l = log 5/7, m = log 7/9 and n = 2( log 3 - log √5) Find the value of L+m+n

Answer 1

Answer:

0

Step-by-step explanation:

given data,

l= log 5/7, m= log 7/9 & n= 2 (log 3 - log root over 5 )

now, l+m+n

substituting the values

=log 5/7 + log 7/9 + log 3^2 - log 5 [ since root of 5 means 5 to the power 1/2 & here '^' is power ]

= log (5/7 × 7 /9) + log 9 - log 5

= log 5 / 9 + log 9/5

=log ( 5/9×9 /5)

= log 1

= 0 ( since log 1 = 0)
