Express as a single logarithm

ln(a)+1/2ln(b)

2ln4-ln2

ln a + (1/2) ln b

= lan a + ln )b^(1/2))
= ln (a√b)

you try the second, and let me know what you got

2ln4-ln2

=ln(16)-ln2
=ln(16/2)
=ln8?

correct

Thank you =)

We are asked to express 2+ln 2 as a single logarithm.Can somebody help me?

To express the given expressions as a single logarithm, we can use the properties of logarithms.

1) ln(a) + 1/2 ln(b):
We can use the property that states ln(a) + ln(b) = ln(ab).
Applying this property, we have:
ln(a) + 1/2 ln(b) = ln(a) + ln(b^(1/2)) = ln(a * b^(1/2))

2) 2ln(4) - ln(2):
We can use the property that states n ln(a) = ln(a^n).
Applying this property, we have:
2ln(4) - ln(2) = ln(4^2) - ln(2) = ln(16) - ln(2)

So, the expressions can be written as:
1) ln(a) + 1/2 ln(b) = ln(a * b^(1/2))
2) 2ln(4) - ln(2) = ln(16) - ln(2)

Note: It is important to simplify further if possible according to the given values of 'a' and 'b'.
