Sorry there should be let before the very first word of the solution given below??

Piyush Kr.?? 6 years, 2 months ago

3 + 2 root 3 is a rational number where a divided by b is the simplest form of 3 + 2 root 3 where no any common factor other than 1. Now, a/b=3+2√3==> 2√3=a-3b/b ==> √3= a-3b/2b...Since a-3b/2b is a rational no. And so √3 is a rational no. But this contradicts the fact that √3 is an irrational...Hence our supposition was wrong and so 3+2√3 is an irrational...??

Find hcf and lcm of 96 & 404

Posted by Kishore Prabakar 6 years, 2 months ago

CBSE > Class 10 > Mathematics

1 answers

Yogita Ingle 6 years, 2 months ago

Since, 96 = 2 × 2 × 2 × 2 × 2 × 3
and, 404 = 2 × 2 × 101
So, HCF of 96 and 404 = Product of common prime factors
= 2 × 2 = 4
LCM = 2 × 2 × 2 × 2 × 2 × 101 × 3
= 9696
