20/x=0.12

20=0.12x

20/0.12=x

x=166.666667

Which expression is equivalent to

rodikova [14]

Step-by-step explanation:

$\log_{12}\left(\dfrac{\frac{1}{2}}{8w}\right)=\log_{12}\left(\dfrac{1}{16w}\right)\qquad\text{use}\ a^{-1}=\dfrac{1}{a}\\\\=\log_{12}(16w)^{-1}\qquad\text{use}\ \log_ab^n=n\log_ab\\\\=-1\log_{12}(16w)\qquad\text{use}\ \log_a(bc)=\log_ab+\log_ac\\\\=-\left(\log_{12}16+\log_{12}w\right)=-\log_{12}2^4-\log_{12}w\qquad\text{use}\ \log_ab^n=n\log_ab\\\\=-4\log_{12}2-\log_{12}w$

The derivative of the given function is, $F'(x)= \frac{-6}{(x+1)^3}$ .The derivative of the function F(x) is F'(x).

<h3>What is differentiation?</h3>

A technique for determining a function's derivative is differentiation. Mathematicians use a procedure called differentiation.

The derivative of the equation is found as;

$F(x)=\rm x^{-2} \\\\ F'(x) = nx^{n-1} \\\\ F(x)=\ \rm (x+1)^{-2} \\\\ F'(x) = -2(x+1)^{-3} \\\\ F'(x) =\frac{2}{(x+1)^3}$

The given function is;

$\rm F(x)= \frac{3}{(x+1)^2} \\\\ F'(x)= \frac{-6}{(x+1)^3}$

Hence, the derivative of the given function is, $F'(x)= \frac{-6}{(x+1)^3}$ .The derivative of the function F(x) is F'(x).
