How to insert an equation with fractions, square roots and exponents

This tip display how to insert an equation for example, the normal, or Gaussian distribution.

How to add an equation in your document, see Working with Microsoft Equation.

To insert, for example, the normal, or Gaussian distribution, do the following:

In the Professional presentation:

    1.    In your own equation enter f(x)=.

    2.    Under Equation Tools, on the Design tab, in the Structures group, click the Fraction button:

    3.    Enter 1 in the top of your fraction.

    4.    In the bottom of your fraction, do the following:

    4.1.    Under Equation Tools, on the Design tab, in the Structures group, click the Radical button. In the Radical list choose Square root:

In the Linear presentation:

    1.    In your own equation enter f(x)=1/.

    2.    Under Equation Tools, on the Design tab, in the Symbols group, choose Radical sign in equations Word 2016 or simply \sqrt.

    3.    In the brackets enter 2  Pi symbol in equations Word 2016 (or \pi), Sigma symbol in equations Word 2016 (or \sigma) and ^2:
