Exponent Calculator to Calculate Base Raised to nth Power

Exponent Calculator Sign

This calculator will calculate the answer of a base number raised to nth power, including exponential expressions having negative bases and/or exponents.

Plus, the calculated results will include either an exponential multiplication chart (for positive exponents) or a decimal conversion chart (for negative exponents).

Note that if you're ever looking to save some time when finding the square root of a number (2√x instead of x2), be sure to check out my Square Root Calculator.

Selected Data Record:

A Data Record is a set of calculator entries that are stored in your web browser's Local Storage. If a Data Record is currently selected in the "Data" tab, this line will list the name you gave to that data record. If no data record is selected, or you have no entries stored for this calculator, the line will display "None".

DataData recordData recordSelected data record: None
Base:Base:Base of exponential expression:Base of exponential expression:

Base of exponential expression:

Enter the base number (integers only) of the exponential expression. For example, in the expression 24, the number two would be the base. If you are entering a negative sign be sure to indicate the parenthesis preference on the next line.

Parenthesis options:

If you are entering a negative sign you will need to select whether or not the negative sign and base are in parenthesis. (-4)2 = 16 whereas -42 = -16 (additive inverse of 42).

Exponent:Exponent:Exponent (base raised to this power):Exponent (base raised to this power):

Exponent (base raised to this power):

Enter the positive or negative integer of the exponential expression (maximum of 500). For example, in the expression 24, the number four would be the exponent.

Result of base raised to entered power:

This is the entered base number raised to the entered exponent.

If you would like to save the current entries to the secure online database, tap or click on the Data tab, select "New Data Record", give the data record a name, then tap or click the Save button. To save changes to previously saved entries, simply tap the Save button. Please select and "Clear" any data records you no longer need.

Exponent Definition

An exponent is the small number located in the upper, right-hand position of an exponential expression (baseexponent), which indicates the power to which the base of the expression is raised.

The following exponential expression shows how the exponent is used in raising the base:

43 = 4 x 4 x 4 = 64

4 x 4 = 16
4 x 16 = 64

Negative Exponents

An exponential expression containing a negative exponent can be translated as follows:

= 0.015625

Negative Bases in Exponential Expressions

One thing to be aware of when working with exponential expressions that have negative signs next to their bases is that a negative sign that is not in parenthesis is different from a negative base that is enclosed by a parenthesis.

(-4)4 = -4 x -4 x -4 x -4 = 256

-44 = -1 x 4 x 4 x 4 x 4 = -256

Adjust Calculator Width:

Move the slider to left and right to adjust the calculator width. Note that the Help and Tools panel will be hidden when the calculator is too wide to fit both on the screen. Moving the slider to the left will bring the instructions and tools panel back into view.

Also note that some calculators will reformat to accommodate the screen size as you make the calculator wider or narrower. If the calculator is narrow, columns of entry rows will be converted to a vertical entry form, whereas a wider calculator will display columns of entry rows, and the entry fields will be smaller in size ... since they will not need to be "thumb friendly".

Show/Hide Popup Keypads:

Select Show or Hide to show or hide the popup keypad icons located next to numeric entry fields. These are generally only needed for mobile devices that don't have decimal points in their numeric keypads. So if you are on a desktop, you may find the calculator to be more user-friendly and less cluttered without them.

Stick/Unstick Tools:

Select Stick or Unstick to stick or unstick the help and tools panel. Selecting "Stick" will keep the panel in view while scrolling the calculator vertically. If you find that annoying, select "Unstick" to keep the panel in a stationary position.

If the tools panel becomes "Unstuck" on its own, try clicking "Unstick" and then "Stick" to re-stick the panel.
