Question

5+√3 is a rational number?​

Answer 1

Answer:

no it is irrational no

Step-by-step explanation:

let is assume that 5+√3 is a rational no in the form of a/b, where b is not equals to 0. and a and b are co- prime no.

5+√3= a/b

√3= a/b - 5

√3= a- 5b/ b

since, a-5b / b is a rational no but as we know that √5 is irrational. so, they cannot be equal

Hence, our assumption that 5+√3 is a rational no is worng. it is irrational no

hope it help.....

hamne jo √3= a -5b/ b liya h wo L.C.M hoga √3= a/b -5 LCM karne ke baad a-5b/b aayega ok mate
