Find 8th term from the end of the A. P - 7,10,13..... 18th |
|
Answer» Correct answer is 37, Explanation :-In this A.P. total terms are 18 so 8th term from last means 11th term from starting. (18-8+1=11th term), Now according to A.P. \'a\' is 7 (first term of A.P.) and \'d\' is 3 (second term - first term = 10-7=3), Using formula :- 11th term = a + 10d = 7 + 10(3) = 7+30 = 37 Answer is 34 Explanation:-- There are 18 terms so 8th term from lats means 18-8 = 10th term.In here,we have a=7 & d=3 So usinga^n= a+(n-1)×d =7+(10-1)×3 = 7+(9×3) = 7+27 =34 |

Prove that √3+√4 is an irrational number |
|
Answer» Lets assume that : √3 + √4 is rational. √3 + √4 = r , where r is rational Squaring both sides , we get [√3 + √4 ]² = r² 3 + 2√12 + 4 = r² 7 + 2√12 = r² 2√12 = r² - 6 √12 = [ r² - 6] / 2 R.H.S is purely rational , whereas , L.H.S is irrational. This is a contradiction. This means that our assumption was wrong. Hence , √3 + √4 is irrational. #Lets assume that :#√3 + √4 is rational.#√3 + √4 = r , where r is rational#Squaring both sides , we get#[√3 + √4 ]² = r²#3 + 2√12 + 4 = r²#7 + 2√12 = r²#2√12 = r² - 6#√12 = [ r² - 6] / 2*R.H.S is purely rational , whereas , L.H.S is irrational.This is a contradiction.This means that our assumption was wrong.*Hence , √3 + √4 is irrational. *note.. # it is for separating steps....
