Question

all formula of real numbers class 10​

Answer 1

Step-by-step explanation:

a=bq+r

HCF(a, b)*LCM(a, b)=a*b

Answer 2

The formulas of Real numbers for the class 10th are given below:

• Euclid's Division Lemma: "Given positive integers a and b, there exist unique integers q and r satisfying a = bq+r," where r is less than b and greater than or equal to zero.
• This theorem can be used to find the HCF of two given numbers.
• HCF (a, b) × LCM (a, b) = a × b where a and b are two positive integers.
• If x is a rational number expressed as a/b where a and b are coprime numbers then b will be equal to the multiplication of powers of 2 and 5.

(Note that in this chapter there is only one formula whereas there are several theorems.)
