**Exponents**

We illustrate with some computations. Press **MENU
1** to access the RUN-MAT screen.

Exponents are entered using the **^** key. For example, 5^{3} is
entered as 5^3.

For
exponents base *e*, press **SHIFT e ^{x}**
(located above the ln key). To compute

For exponents base 10, press **SHIFT 10 ^{x}**
(located above the log key). To compute 10

There is a special cube root key located above the ( key. To find the cube
root of 531, press **SHIFT ^{3}**

To compute a radical or numerical root, one may use the general root key (located above the ^ key) or use the algebraic equivalence that . For example, to compute , press

**5 SHIFT ^{x}**
