In mathematics, a square root of a number x is a number y such that y 2 = x; in other words, a number y whose square (the result of multiplying the number by itself, or y ⋅ y) is x. For the elements of X that are negative or complex, sqrt(X) produces complex results. is absolutely convergent. So the answer would be 2. Putting these two facts together gives the following, $A \approx \sum\limits_{n = 1}^\infty {\frac{1}{n}} > \int_{{\,1}}^{{\,\infty }}{{\frac{1}{x}\,dx}} = \infty$ Notice that this tells us that we must have, $\sum\limits_{n = 1}^\infty {\frac{1}{n}} > \infty \hspace{0.5in} \Rightarrow \hspace{0.5in}\sum\limits_{n = 1}^\infty {\frac{1}{n}} = \infty$ Since we can’t really be larger than Find a perfect square that is a multiple of 18: in this case it would be 9, because 9 x 2 = 18.
