Question

suppose ln2= r and ln5= s . use properties of logarithms to write the logarithm in terms of r and s.
Ln2.5

Answer 1

use ln2+ln5=ln(2*5)

Answer 2

i think you should use
\[\ln(2.5)=\ln(\frac{5}{2})=\ln(5)-\ln(2)=s-r\]

Answer 3

so is it s+r or s-r?

Answer 4

its s-r if 2.5is 5/2 or s+r if 2.5 is 2*5=10

Answer 5

Ok thanks i think i will write s+r
