Firstly, solve the subtraction: [tex] \sqrt{(\frac{18}{5})^2+(\frac{1}{3})^2} [/tex]
Next, solve the exponents: [tex] \sqrt{\frac{324}{25}+\frac{1}{9}} [/tex]
Next, we need to find the LCM of 9 and 25. To find the LCM, or least common multiple, find the lowest common number that they both multiply to. In this case, it's 225. Multiply 3234/25 by 9/9 and 1/9 by 25/25: [tex] \frac{324}{25}*\frac{9}{9}=\frac{2916}{225}\\\\ \frac{1}{9}*\frac{25}{25}=\frac{25}{225}\\ \\ \sqrt{\frac{2916}{225}+\frac{25}{225}} [/tex]
Next, add the two fractions together, and your exact distance is [tex] \sqrt{\frac{2941}{225}} [/tex] (or approximately 3.62, rounded to the hundreths, if you square root the fraction.)
