# How to do exponent in java

## How do I do exponents?

The exponent “product rule” tells us that, when multiplying two powers that have the same base, you can add the exponents. In this example, you can see how it works. Adding the exponents is just a short cut! The “power rule” tells us that to raise a power to a power, just multiply the exponents.

## How do you find the exponent of a number in Java?

Read the base and exponent values from the user. Multiply the base number by itself and multiply the resultant with base (again) repeat this n times where n is the exponent value.

## How do you write squared in Java?

Squaring a number in Java can be accomplished in two ways. One is by multiplying the number by itself. The other is by using the Math. pow() function, which takes two parameters: the number being modified and the power by which you’re raising it.

## How do you calculate exponents quickly?

Write: 6 6 6, because the base number is 6 and the exponent is 3. Then write: 6 x 6 x 6, to place multiplication signs between each of the base numbers. After that, multiply out the first multiplication sign, or 6 x 6 = 36. Then, multiply out the final multiplication sign to get 36 x 6 = 216.

## How do you cube in Java?

Cube of a value is simply three times multiplication of the value with self. For example, cube of 2 is (2*2*2) = 8.

Java program to find a cube of a given number

1. Take integer variable A.
2. Multiply A three times.
3. Display result as Cube.

## How do you find the power of a number?

Calculating Powers

In XY calculations the base represents the number and the exponent the amount of times the number will be multiplied by itself. For example: If 4 is the base number and the exponent is 3, the occasion would be 4 x 4 x 4, or 64, the equation can also be understood as 4 to the power of 3, also 64.

## What is a modulus in Java?

Java has one important arithmetical operator you may not be familiar with, % , also known as the modulus or remainder operator. The % operator returns the remainder of two numbers. For instance 10 % 3 is 1 because 10 divided by 3 leaves a remainder of 1.

## What is NaN in Java?

In Java, “NaN” stands for “not a number” and signifies that a value is not defined. “NaN” is not an exception error, but a value that is assigned. For example, imaginary numbers like the square root of negative numbers or zero divided by zero will both print “NaN” as the result.

## What is happy number in Java?

Introduction to Happy Numbers in Java. Happy Number are positive non-zero integer numbers. If we find the sum of the squares of its every digit and repeat that process until the number will be equals to 1(one). Otherwise, it is called Unhappy Number or Sad Number.

## How do you divide in Java?

// Divide a literal by a literal; result is 5 int result = 10 / 2; // Divide a variable by another variable; result is 3 int a = 15; int b = 5; int result = a / b; When dividing integer types, the result is an integer type (see the previous chapter for the exact data type conversions for mathematical operations).
