Refer to Figure 10.18, and use these steps:
1. Create an equation with an even exponent and a negative base value.
Click the Parens menu item. Then click in the equation composition area
to position the parentheses. Pull the parentheses apart far enough to
accommodate a field for a value.
2. Click the Subtract menu item. Then click inside the parens in the equa-
tion composition area to create a minus sign (
). Move the minus sign
snugly against the left parenthesis.
3. Click on the Value item in the menu. In the equation composition area
just after the minus sign, click to place the Value field inside the parens.
In this field, type x.
4. Click on the menu item for Power (or exponent). Then place the field for
the exponent to the upper right of the closing parenthesis. Type a 6 in the
Exponent field.
