Quizplus · Accepted Answer

To simplify the expression, first, make the denominators the same for the first two terms by multiplying the numerator and denominator of the second term by $\sqrt{7}$, giving $\frac{\sqrt{7}}{7} + \frac{2\sqrt{7}}{7}$. The third term, $\sqrt{28}$, simplifies to $2\sqrt{7}$. Combining these, we get $\frac{3\sqrt{7}}{7} + 2\sqrt{7}$, which simplifies further to $\frac{3\sqrt{7} + 14\sqrt{7}}{7} = \frac{17\sqrt{7}}{7}$.
