This is very easy You have to solve it by contradictory method. You have to prove ur statement wrong in this question Let if possible 7√5 is a rational number =7√5=a/b =√5=a/5b both a and b are integers so that a/5b is rational and so √5 is also rational This contradicts the fact that√5 is irrational number. This assumption is wrong so 7√5 is irrational.

Let us assume that 7√5 is rational number Hence 7√5 can be written in the form of a/b where a,b(b is not equal to 0) are co-prime ⟹7√5=a/b ⟹√5=a/7b But here √5 is irrational and a/7b is rational as Rational is not equal to Irrational This is a contradiction so 7√5 is a irrational number

The small intestine has millions of tiny finger-like projections called villi . These villi increase the surface area for more efficient food absorption. Within these villi, are present numerous blood vessels that absorb the digested food and carry it to the bloodstream. It is hence from the bloodstream, the absorbed food is delivered to each and every cell of the body.

Prove that 4-3✓2 is an irrational number

Posted by Marzia Ahmad Zaidi 5 years, 2 months ago

CBSE > Class 10 > Mathematics

1 answers

Swarnamudra Sahu 5 years, 2 months ago

Let us assume that 4-3root 2 is rational So we can write 4-3root 2 as a/b where a and b are co prime & b is not equal to 0 4-3 root 2=a/b -3root 2 =a/b -4 -3root 2=a-4b/b root 2 = a-4b/3b root 2=-a-4b /3b Here root 2 is an irrational number. But a-4b/-3b or -a-4b/3b is rational number. Therefore it is a contradiction to our assumption that 4-3 root 2 is a rational number. Thus 4-3 root 2 is irrational number Hope it helps
