-1 = (x-1)/3
(multiply both sides by 3)
-3 = x-1
(add 1 on both sides)
x=-2

Expanding Logarithmic Expressions In Exercise, use the properties of logarithms to rewrite the expression as the sum, difference
kicyunya [14]

Answer:

\\ ln(x^2) - ln(x^2 + 1).

For values of x>0, it can be rewritten as \\ 2ln(x) - ln(x^2 + 1).

Step-by-step explanation:

For the expression:

\\ ln(\frac{x^2}{x^2 + 1})

We can apply this logarithmical property: \\ ln(\frac{x}{y}) = ln(x) - ln(y).

Then,

\\ \frac{x^2}{x^2 + 1} = ln(x^2) - ln(x^2 + 1).

If we assume values of <em>x </em>> 0 (non negative values for x), then the expression could be rewritten as follows:

\\ \frac{x^2}{x^2 + 1} = ln(x^2) - ln(x^2 + 1) = 2 ln(x) - ln(x^2 + 1), since \\ ln(x^{n}) = n*ln(x).

We have to remember that <em>domain</em> (all possible values x) for logarithmic function is for all x > 0, or mathematically expressed as:

Domain: \\ {x | x \in R, x > 0}

Simplify completely.<br><br> (h^12h^4)^3
hichkok12 [17]
(h^{12}h^4)^3
You need to work inside out. (h^{12}h^4) simplifies to h^{16}.
Now you need to cube that. (h^{16})^3 = h^{48}
Therefore the solution is h^{48}.
