Q. Given the substitutions ln2=a,ln3=b, and ln5=c, find the value of ln(3e) in terms of a,b, and c.Answer:
Express ln(3e): Express ln(3e) using the properties of logarithms.We know that ln(e)=1 because the natural logarithm of e to the power of 1 is e. We also know that ln(3)=b. Using the quotient rule for logarithms, which states that ln(yx)=ln(x)−ln(y), we can write ln(3e) as ln(e)−ln(3).
Substitute known values: Substitute the known values into the expression.Substitute ln(e)=1 and ln(3)=b into the expression from Step 1.ln(3e)=ln(e)−ln(3)=1−b
Simplify expression: Simplify the expression.Simplify the expression to get the final answer in terms of a, b, and c.ln(3e)=1−bSince there are no terms involving a or c, the expression remains as is.
