Solving expressions that has rational numbers as exponents (CBSE Class-9 Daily Math)
Просмотров 9493 года назад
We learn how to apply laws of exponents we have learned in previous classes to expressions that have positive real number as base and exponents that are in the form of rational numbers.
Find 5 rational numbers between -1/5 and 2/3 (CBSE Class-8 Daily Math Videos)
Просмотров 60 тыс.3 года назад
We learn how to find 5 rational numbers between -1/5 and 2/3. We also learn that average or arithmetic mean of two numbers say a and b is (a b)/2 and that a is less than (a b)/2 is less than b. We can use the average method (described above) or another method whereby we express given rational numbers in equivalent form and then find rational numbers in between them.
Prove √3, 3√5, and 5 - √7 are Irrational Numbers (CBSE Class-10 Daily Videos)
Просмотров 1,3 тыс.3 года назад
Welcome! In this video, we learn how to prove numbers such as √3, 3√5, and 5 - √7 are indeed irrational numbers. We go through detailed step-by-step analysis. We look at a very important theorem that we use (that theorem is based on The Fundamental Theorem of Arithmetic). We prove such problems by method of Contradiction. These problems typically carry 3-marks in CBSE Class-10 board exams.
Rationalize denominator of Irrational Number (CBSE Class-9 Daily Math Number Systems)
Просмотров 1,2 тыс.3 года назад
We learn how to rationalize the denominator of an irrational number. We review some of the identities that we use to solve these problems. We have also studied how to find √2, √5, and √10 irrational numbers on number-line earlier. Also, we know now to find irrational numbers between given rational numbers.
Solving Rational number problems by applying all the properties (CBSE Class-8 Daily Videos)
Просмотров 1,9 тыс.3 года назад
We learn how to solve rational number problems. We apply all the properties we have learnt so far such as closure, commutativity, associativity and distributivity of rational numbers. We also apply the order of operations correctly.
Terminate or Not? How many decimal places? (CBSE Class-10 Daily Videos)
Просмотров 8133 года назад
We learn whether the decimal expansion of rational number terminates or not without actually carrying out the long division. This type of questions in CBSE Class-10 board exam carries 1-mark. After finding out that decimal expansion terminates, we will learn how we can tell how many decimal places in the expansion.
