Why is 2^16 a "special" number? [closed] - Software Engineering …
For a long time CPUs used 16-bit architecture and OSes were likewise based on 16-bit operations and "words". There were 16-bit commands and 16-bit memory addresses. A lot of systems/compilers still use 16 bits for integers. So, (2 16 - 1) is special because it is the largest number that a 16-bit (unsigned) integer can hold and the largest ...
Formula, Examples | How to Find/Calculate Square Root? - Cuemath
The square root formula is used to find the square root of a number. We know the exponent formula: n√x x n = x 1/n. When n = 2, we call it square root. We can use any of the above methods for finding the square root, such as prime factorization, and so on. 9 …
Equation of Circle - Formula, Examples | Circle Equation - Cuemath
Example 3: Find the equation of the circle in the polar form provided that the equation of the circle in standard form is: x 2 + y 2 = 16. Solution: To find the equation of the circle in polar form, substitute the values of x and y with: x = rcosθ y = rsinθ. x 2 + y 2 = 16 (rcosθ) 2 + (rsinθ) 2 = 16. r 2 cos 2 θ + r 2 sin 2 θ = 16. r 2 (1 ...
Standard Form to Vertex Form - Formula, Examples, FAQs - Cuemath
y = −3x 2 − 6x − 9 = −3 (x 2 + 2x + 3) Now, the coefficient of x 2 is 1. Here are the steps to convert the above expression into the vertex form. Step 1: Identify the coefficient of x. Step 2: Make it half and square the resultant number. Step 3: Add and subtract the above number after the x term in the expression.
Lowest Common Multiple | How to Find LCM? - Cuemath
Step 2: Mark the common multiples from the multiples of both numbers. Step 3: Select the smallest common multiple. That lowest common multiple is the LCM of the two numbers. Example: Find the least common multiple (LCM) of 4 and 5. Solution: The first few multiples of 4 are: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, ...
Square Root Function - Graph, Domain, Range, Examples - Cuemath
4 2 = 16 ⇒ √16 = 4 We know that the square root of a number can be either positive or negative. i.e.,√4 = ±2. But while defining the square root function, we restrict its range to be the set of all positive real numbers (otherwise it won't become a function at all), and hence in the case of the square root function, the result is always ...
Square 1 to 50 | Values of Squares from 1 to 50 [PDF Download]
In order to calculate the squares from 1 to 50, we can use any one of the following methods: Method 1: Multiplication by itself. Method 2: Using basic algebraic identities: To find the square of 34, we can express 34 as: Option 1: (30 + 4) Option 2: (40 - 6) In the next step, we use the basic algebraic identity formula and get Option 1: [30² ...
8 Times Table - Learn Table of 8 | Multiplication Table of Eight
Example 2: Check using the table of 8 whether 8 times 2 minus 6 is 10. Solution: First, we will write 8 times 2 minus 6 mathematically. Using 8 times table, we have: 8 times 2 minus 6 = 8 × 2 - 6 = 16 - 6 = 10. Hence, 8 times 2 minus 6 is 10. Example 3: Using 8 times table, find the value of 8 times 3 minus 10 plus 9.
Prime Numbers 1 to 50 | List of Prime Numbers Between 1 to 50
In order to find the probability of choosing one prime number from 1 to 50, we need to first list the prime numbers from 1 to 50 and then find their total. The list of prime numbers that are less than 50 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, and 47. We can see that there are 15 prime numbers less than or equal to 50.
What are Even Numbers? Definition | Odd and Even Numbers
Even numbers are those numbers that can be divided into two equal groups or pairs and are exactly divisible by 2. For example, 2, 4, 6, 8, 10, and so on are even numbers. These numbers can be grouped in equal pairs. However, this grouping cannot be done for numbers like 5, 7, 9, or 11. So, 5, 7, 9, or 11 are not even numbers.
