- Integers - Definition | Meaning | Examples | What are Integers? - Cuemath
Here, the absolute values of 2 and (-5) are 2 and 5 respectively Their difference (larger number - smaller number) is 5 - 2 = 3 Now, among 2 and 5, 5 is the larger number and its original sign “-” Hence, the result gets a negative sign, "-” Therefore, 2 + (-5) = -3 Example: Add the given integers: (-2) + 5 Solution:
- Exponent Rules | Laws of Exponents | Exponent Rules Chart - Cuemath
Example 2: Simplify the given expression and select the correct option using the laws of exponents: 10 15 ÷ 10 7 (a) 10 8 (b) 10 22 Solution: As per the exponent rules, when we divide two expressions with the same base, we subtract the exponents This means, 10 15 10 7 = 10 15 - 7 = 10 8 Therefore, the correct option is (a) 10 8 Answer
- Prime Numbers 1 to 100, Examples | Prime Numbers List - Cuemath
The factors of 18 are 1, 2, 3, 6, 9 and 18; and the factors of 35 are 1, 5, 7 and 35 We can see that they have only 1 as their common factor, therefore, they are coprime numbers It should be noted that Co-prime numbers need not necessarily be prime numbers Examples of Prime Numbers A few examples of prime numbers are 2, 3, 5, 7, and so on
- Arithmetic Sequence - Formula, Definition, Examples, Applications . . .
For example, 1, 3, 5, 7, is an arithmetic sequence as every term is obtained by adding 2 (a constant number) to its previous term How to Identify An Arithmetic Sequence? If the difference between every two consecutive terms of a sequence is the same then it is an arithmetic sequence
- Median - Formula, Meaning, Example | How to Find Median? - Cuemath
= (7 + 1) 2 th term = 4 th term = 42 Median = 42 Median Formula for Grouped Data When the data is continuous and in the form of a frequency distribution, the median is calculated through the following sequence of steps Step 1: Find the total number of observations(n) Step 2: Define the class size(h), and divide the data into different classes
- NCERT Solutions Class 10 Maths Chapter 7 Exercise 7. 2 - Free PDF
NCERT solutions for class 10 maths chapter 7 exercise 7 2 Coordinate Geometry is purely based on the section formula The exercise explains this concept with the help of a simple example Suppose a telephone company wants to position a relay tower at L between A and B in such a way that the distance of the tower from B is twice its distance from A
- Quadratic Equations - Formulas, Methods, and Examples - Cuemath
The given quadratic equation is 2x 2 + 9x + 7 = 0 Hence the required equation having reciprocal roots is 7x 2 + 9x + 2 = 0 Method 2: From the given equation, α + β = -9 2 and α β = 2 7 The new equation should have its roots to be 1 α and 1 β

= 8x 3 + 5x 2 + 6x - 5 Example 3: Simplify the given expression 8x 4 - 4x 2 + 4x 3 + 2x - 4x 2 + 7 - 3x Solution: = 8x 4 - 4x 2 + 4x 3 + 2x - 4x 2 + 7 - 3x = 8x 4 + 4x 3 - (4x 2 + 4x 2) + (2x - 3x) + 7 = 8x 4 + 4x 3 - 8x 2 - x + 7 Similarly, you can try the calculator to simplify the expressions for the following: 5cos 2 x + 6sin 2 x + 5sin
- What is 7 2 as a decimal? - Cuemath
Here, the fraction is 7 2 which means we need to perform 7 ÷ 2 Since the dividend is not perfectly divisible, we have to put the decimal in the quotient By proceeding with the long division method we have obtained 7 2 as a decimal is 3 5 This gives the Quotient as 3 5 and Remainder equal to 0 So, 7 2 as a decimal is 3 5 You can also
