Answer:

To solve this, we will need to use log properties. We know that subtracting two log equations gives us:

[tex]log\frac{5x^{3} }{x^{2} } =2[/tex]

If log base 10 equals 2, we know that [tex]\frac{5x^{3} }{x^{2} }[/tex] equals 100. We can solve this by:

[tex]\frac{5x^{3} }{x^{2} }[/tex] = 100

5x³=100x²

x³= 20x²

x³-20x²=0

x²(x-20)=0

Thus, the answer is x=20.
