Thanks so much teacher for teach us nicely

[Itzzdatopper]

Please please can someone explain me
When the question is 1.254 = the answer we are getting is 0983
So when we are writing it, are we gonna write it like this 👇
lg 1.254 = 0.0983 or this 👇
lg 1.254 = 0.983
Because teacher does it differently in various questions
Same for 3.752 = 0.05742 = lg 3.752 = 0.05742 or 0.5742
