Work: Calculate the value of equation lg14-2*lg(7/3)+lg7-lg18 .
Question type: Mathematical calculation
Solution:
lg14-2*lg(7/3)+lg7-lg18
=lg14-2*lg2.333333+lg7-lg18
=1.146128-2*lg2.333333+lg7-lg18
=1.146128-2*0.367977+lg7-lg18
=1.146128-2*0.367977+0.845098-lg18
=1.146128-2*0.367977+0.845098-1.255273
=1.146128-0.735954+0.845098-1.255273
=0.410174+0.845098-1.255273
=1.255272-1.255273
=-0.000001
Answer:lg14-2*lg(7/3)+lg7-lg18=-0.000001
