[latex] frac{2}{9x^3} + frac{5}{3x} [/latex] Find the LCD .  Factor each denominator  into its primes 9 = 3² Find the least common denominator 3²x³ = 9 x³ Adjust fractions based  on the LCD: [latex] frac{2}{9x^3} + frac{5*3x^2}{9x^3} [/latex] Since the denominators are equal, combine the fractions : [latex] frac{2+3*5x^2}{9x^3} [/latex] Simplify  2+3*5x² multiply the numbers : 3 * 5 = 15 2  + 15 x² [latex] = frac{2+15x^2}{9x^3} [/latex] hope this helps!
