Q. Given the substitutions ln2=a,ln3=b, and ln5=c, find the value of ln(2725) in terms of a,b, and c.Answer:
Rewrite using substitutions: Given that ln2=a, ln3=b, and ln5=c, we need to express ln(2725) using these substitutions.First, we can rewrite 25 as 52 and 27 as 33.So, ln(2725) becomes ln(3352).
Separate terms in logarithm: Using the properties of logarithms, we can separate the terms in the logarithm. ln(3352)=ln(52)−ln(33).
Apply power rule of logarithms: Now, apply the power rule of logarithms, which states that ln(xy)=y⋅ln(x). This gives us 2⋅ln(5)−3⋅ln(3).
Substitute given values: Substitute the given values for ln(5) and ln(3). This results in 2×c−3×b.
Final answer: The expression 2×c−3×b is the final answer in terms of a, b, and c.
