Given : u = 4  and v = 3

To Find : log (u + v)/(u² -  v²)

Solution:

log (u + v)/(u² -  v²)

(u² -  v²)   = ( u + v) ( u - v)

Hence  (u + v)/(u² -  v²) = 1/( u - v)

log (u + v)/(u² -  v²)

= log ( 1/(u - v)(

u = 4 and v = 3

= log ( 1/(4 - 3))

= log ( 1/1)

= log 1

= 0

if its log (u + v) (u² -  v²)

= log ( 7)(7)

= log 7²

= 2 log 7

= 2 ( 0.8451)

= 1.6902
