hello :
ln x + 2 ln 5 + ln 1 = lnx+ln5² +ln1
                             = ln(25x) ...because : ln1 = 0
                                                              
lnx+ln5² = ln(x×25) 

The simplified expression is In (25x). Option D shows the simplified expression of the given equation.

Further Explanation On Logarithm

The given expression is,

[tex]In \; x + 2 In \; 5 + In \; 1[/tex]

We will use the basic properties of the logarithm to simply the given expression.

The Basic Properties of Logs are,

[tex]log_b(xy) = log_b\;x + log_b\;y.[/tex]

[tex]log_b(x/y) = log_b\;x - log_b\;y.[/tex]

[tex]log_b(xn) = n log_b\;x.[/tex]

[tex]log_b\;x = log_a\;x / log_a\;b.[/tex]

[tex]log \;1= 0[/tex]

By using 3rd and 5th property, we simply the given expression as,

[tex]In\; x + In \; 5^2 + 0[/tex]

[tex]In \; x + In \; 25[/tex]

By using the first property, we get the expression,

[tex]In \; x + In \; 25[/tex]

[tex]In \; (x \times 25)[/tex]

[tex]In \;25x[/tex]

Hence the simplified expression is In (25x). Option D shows the simplified expression of the given equation.
