Answer:

$3^{ -x+3}$

Step-by-step explanation:

We need to simplify out the given exponential expression . The given expression to us is ,

$\rm\implies \dfrac{\dfrac{1}{3}}{3^{x-4}}$

We can use the Law of Exponents to simplify the given expression . Recall that ,

$\rm\implies \red{\dfrac{a^m}{a^n}= a^{m-n}}$

Note that , we can write ,

$\rm\implies \dfrac{1}{3}= 3^{-1}$

Therefore our expression becomes ,

$\rm\implies \dfrac{ 3^{-1}}{3^{x-4}}$

Simpify using the Law of Exponents ,

$\rm\implies 3^{ -1 - ( x - 4 )}$

Open the brackets in exponent ,

$\rm\implies 3^{ -1 - x +4 }$

Simplify to get final expression ,

$\rm\implies \boxed{\quad \blue{ 3^{-x+3} \quad}}$

$-7-x= 3 \\ \\ -x= 3+7\quad \to -x= 10\to \boxed{x=10} \\ \\ \\ -7-x= 8 \\ \\ -x= 8+7\quad -x= 15\to \boxed{x= -15}$

$-\dfrac{17}{6}x+1=\dfrac{7}{6}-\dfrac{5}{2}x\\\\\text{Most people do not like fractions. Well, let's get rid of them.}\\\\\text{Find the common denominator.... It's 6 :)}.\\\\\text{Multiply both sides of the equation by 6:}\\\\6\!\!\!\!\diagup^1\cdot\left(-\dfrac{17}{6\!\!\!\!\diagup_1}x\right)+6\cdot1=6\!\!\!\!\diagup^1\cdot\dfrac{7}{6\!\!\!\!\diagup_1}-6\!\!\!\!\diagup^3\cdot\dfrac{5}{2\!\!\!\!\diagup_1}x\\\\-17x+6=7-3\cdot5x\qquad\text{subtract 6 from both sides}$

$-17x=1-15x\qquad\text{add 15x to both sides}\\\\-2x=1\qquad\text{divide both sides by (-2)}\\\\\boxed{x=-\dfrac{1}{2}}$
