Answer 1

Expression on single algorithm

7.

ln 4+ln 3x

ln 4*3x

=ln 12x

8.½ln 256 -3 ln 2

`ln(256) {}^{ (1)/(2) } - ln {2}^(3)`

`ln {16}^{ (2)/(2) } - ln8`

`ln \: (16)/(8)`

ln 2

9.

7 ln a -4 ln b

`ln \: {a}^(7) - ln \: b {}^(4)`

`ln \: \frac{ {a}^(7) }{ {b}^(4) }`

Note:

coefficient is a power

and

divide when there is subtract[-]

multiply when there is addition [+]
