2ln(6) - 4ln(5)
= 2[ln(6) - 2ln(5)]
= 2[ln(6) - ln(5^2)]
= 2ln(6/25)
= -2.85423271
= 2[ln(6) - 2ln(5)]
= 2[ln(6) - ln(5^2)]
= 2ln(6/25)
= -2.85423271

2 ln 6 - 4 ln 5
= ln 6^2 - ln 5^4
= ln (6^2 / 5^4)
= ln (36/625)
= -2.8542 (4dp)
= ln 6^2 - ln 5^4
= ln (6^2 / 5^4)
= ln (36/625)
= -2.8542 (4dp)

Just plug the numbers in you calculator.
2ln6 = 3.583518938 and
4ln5 = 6.43775165 so,
2ln6 - 4ln4= (3.583518938) - (6.43775165)= -2.854232711
So, -2.854232711 is the exact value
