If sum of m terms of an AP is equal to sum of n terms of an AP. Then prove that Sum of n+m terms = 0 |
| Answer» Let a be the first term and d be the common difference of the given A.P. Then, Sm = Sn{tex}\\Rightarrow \\quad \\frac { m } { 2 } \\{ 2 a + ( m - 1 ) d \\} = \\frac { n } { 2 } \\{ 2 a + ( n - 1 ) d \\}{/tex}{tex} \\Rightarrow{/tex}\xa02a (m - n) + {m (m - 1) - n (n - 1)} d = 0{tex} \\Rightarrow{/tex} 2a (m - n) + {m2 - m - n2 + n}d = 0{tex} \\Rightarrow{/tex}\xa02a (m - n) + {(m2 - n2) - (m - n)} d = 0{tex} \\Rightarrow{/tex}2a (m - n) + {(m\xa0 - n) (m +n) - (m - n)} d = 0{tex} \\Rightarrow{/tex}\xa0(m - n) {2a + (m + n - 1)d} = 0{tex} \\Rightarrow{/tex}\xa02a + (m + n - 1)d = 0\xa0{tex} [ \\because m - n \\neq 0 ]{/tex}\xa0...(i)Now,\xa0{tex} S _ { m + n } = \\frac { m + n } { 2 } \\{ 2 a + ( m + n - 1 ) d \\} = \\frac { m + n } { 2 } \\times {/tex}0 = 0 [Using\xa0(i)] | |

Prove that 2 is rational |
| 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.. | |
