What Is a Laws of Exponents Calculator?

A Laws of Exponents Calculator is an online tool which can solve your exponents-related mathematical problems.

Numbers with exponents are frequently observed in fields of science and mathematics. Most solutions to real-life problems use exponent laws. For instance, using prefixes in physics to perform basic operations on large values.

Similarly, measurement units to represent quantities are in the form of exponents. Like determining the area in square feet or volume in cubic meters. That’s why we need such a tool that can fastly solve these problems

How Does the Laws of Exponents Calculator Work?

The Laws of Exponents Calculator works by taking the input expression and applying the appropriate law of exponent to find the answer to this expression.

The working of this calculator is based on fundamental laws of exponents, so we need to discuss the exponents and their laws to further understand the operation of this calculator.

What Are the Exponents?

Exponents are the values written in the power of a number. This describes how many times this number should multiply by itself. This number being multiplied is called the base. These numbers can be represented as $x^{n}$.

For example, a base y is raised to the power 3, then the expression to solve this number is as follows.

$y^{3}$ = y x y x y 

To simplify the expression having such terms, there are seven basic laws often used. Let’s discuss them one by one briefly.

Product Law

The product law of exponent states that two terms are multiplied with identical bases and different powers then add both powers. For instance, if $x^{a}$ is being multiplied with $x^{b}$ then the result of multiplication can be written as:

\[ x^{a} \times x^{b} = x^{a+b} \]

This needs to be noted if the bases are also different then each of the terms is solved separately and multiplied.

Quotient Law

The quotient law of exponents says that if two expressions with the same bases and different exponents are divided, then subtract both exponents. Let’s say an expression $y^{c}$ is divided by another expression which is $y^{d}$ then it can be represented as:

\[ \frac{x^{a}}{x^{b}} = x^{a-b} \]

Here the exponent in the denominator is always subtracted from the exponent in the numerator.

Power of a Power

This law states that if the power in a term is raised to another power, then simply multiply both powers. For example, the power a in term $z^{}$ is raised to another power let’s suppose b, then it can be expressed as:

\[ z^{a^{b}} = z^{a x b} \]

Power of Product

According to the power of product law, if the base is a product of two numbers then the result can be obtained by distributing the exponent to each of the numbers in the base separately. See the below expression to further clarify this concept.

\[ (xy)^{b} = x^{b} \cdot y^{b} \]

Power of Quotient

If the base is in the form of a fraction of two numbers, then assign the power to the numerator and denominator of the base individually. This is known as the Power of Quotient Law.

Let’s take an example to understand it, an expression $\frac{y}{z}$ has a single power which is c. Then it can be written as:

\[ (\frac{y}{z})^{c} = \frac{ y^{c} }{ z^{c} } \]

Negative Exponent Law

The negative exponent law states that if a base has a negative exponent then to make it positive write this expression in the denominator of a fraction with the numerator equal to 1. For instance, the term $x^{- d}$ can be expressed as:

\[ x^{- d}= \frac{1}{ x^{d} } \]

Zero Exponent Law

This law simply states that if any base has power equal to zero, then the result of such expression is 1. This can be written as:

$z^{0}$ = 1 

No matter what number the z is, if the exponent is zero, it will be equal to one always.

Solved Examples

There are some examples solved by the Laws of Exponents Calculator. Each example is explained in detail.

Example 1

Simplify the following mathematical expression using the laws of the exponents.

\[ 3^{8} x 3^{3} \]


This expression simplified by this calculator is given below. It performs the addition of both exponents and multiplies the base the resultant sum times by itself that is product law.

\[ 3^{8} x 3^{3}  =  3^{11} = 177147 \]

Example 2

A student in a maths exam is given the below expression:

\[ \frac{12x^{4}}{4x^{2}}  \]

He is asked to simplify the expression and find the answer to the expression.


The expression is a fraction with terms that have a constant number multiplied by a variable with some exponent. The constants are treated separately whereas the variable is the same, so the quotient law is applied to the variable part.

\[ \frac{12x^{4}}{4x^{2}} =  3x^{2} \]

As the expression involves variables, so it plots the simplified expression in the x-y plane. The plot can be seen in figure 1.
