<h3>Answer: 8</h3>

=====================================

Work Shown:

$y = 192\left(4^{x-3}\right)\\\\196,608 = 192\left(4^{x-3}\right)\\\\\frac{196,608}{192} = 4^{x-3}\\\\1024 = 4^{x-3}\\\\4^{x-3} = 1024\\\\\log\left(4^{x-3}\right)=\log\left(1024\right)\\\\(x-3)*\log\left(4\right)=\log\left(1024\right)\\\\x-3=\frac{\log\left(1024\right)}{\log\left(4\right)}\\\\x-3=5\\\\x=5+3\\\\x=8\\\\$

Please help!!!! BRAINLIEST for whoever is correct!! What is the difference of the rational expressions below?

Nostrana [21]

Answer:

Step-by-step explanation:

$\frac{x + 5}{ {x}^{2} } - \frac{2}{5x}$

Write all the numbers above the least common denominator ${5x}^{2}$

$\frac{5(x + 5) - 2x}{5 {x}^{2} }$

Distribute 5 through the parentheses

$\frac{5x + 25 - 2x}{5 {x}^{2} }$

Collect like terms

$\frac{3x + 25}{5 {x}^{2} }$

Hope this helps...

Good luck on your assignment...
