To proved root 2 is an irrational number. |
|
Answer» Let\xa0√2 be a rational number\xa0Therefore,\xa0√2= p/q [ p and q are in their least terms i.e., HCF of (p,q)=1 and q\xa0≠ 0On squaring both sides, we get\xa0 p²= 2q² ...(1)Clearly, 2 is a factor of 2q²⇒ 2 is a factor of p² [since, 2q²=p²]⇒ 2 is a factor of p\xa0Let p =2 m for all m ( where m is a positive integer)Squaring both sides, we get\xa0 p²= 4 m² ...(2)From (1) and (2), we get\xa0 2q² = 4m² ⇒ q²= 2m²Clearly, 2 is a factor of 2m²⇒ 2 is a factor of q² [since, q² = 2m²]⇒ 2 is a factor of q\xa0Thus, we see that both p and q have common factor 2 which is a contradiction that H.C.F. of (p,q)= 1 Therefore, Our supposition is wrongHence\xa0√2 is not a rational number i.e., irrational number.

Can anyone tell me when to use distance and when to use section formula? |
|
Answer» Ikrar is my elder brother We use distance formula for finding the distance between two points (like distance between A to B )& we use section formula to find the rotio of the sector of line which is divided into two (or more) parts , for ex; suppose AB is a line and P is the point on AB so by section formula we can find the distance AP and BP and its coordinates also. To find the distance btw two point ......if we have to find the ratio in which line joining btw two coordinate is divided by a coordinate we use section formula..... |
