What is the reciprocal of $\frac{2}{3}$? The reciprocal of $\frac{2}{3}$ is $\frac{3}{2}$. $$ \text{The reciprocal of } \frac{2}{3} \text{ is } \frac{3}{2} $$ What Does Reciprocal Mean? The word reciprocal in mathematics means the number which, when multiplied by the original number, results in 1. So for this example: $$ \frac{2}{3} \times x = 1 $$ To solve for $x$, isolate it by dividing both sides by $\frac{2}{3}$: $$ \begin{align} \frac{2}{3} \times x &= 1 \ \frac{2}{3} \div \frac{2}{3} \times x &= 1 \div \frac{2}{3} \ x &= 1 \times \frac{3}{2} \ x &= \frac{3}{2} \end{align} $$ ...

What is the square root of 0? Or written mathematically: $$ \sqrt{0} \ ? $$ The square root of 0 is 0. $$ \sqrt{0} = 0 $$ To learn how you can obtain this answer, let’s explain the concept of a square root first. What Is A Square Root? Squaring a number is where you take that number and multiply it by itself: $$ x \times x = x^2 $$ ...

If you’re studying mathematics, you may have come across the term vinculum. A vinculum is a horizontal line that is placed over an expression to indicate that it is to be considered as a single unit. The fraction bar and the square root sign are expressions that you might already be familiar with but perhaps weren’t aware a vinculum was used. For example, with the expression $\sqrt{25}$, the vinculum is the horizontal line that is placed over the number $25$. Or with the expression $\frac{1}{2}$ the vinculum is the horizontal line that separates the numerator and the denominator. ...
