Question

2+root 3 is a rational or irrational explain step wise​

Answer 1

Answer:

to prove that 2+√3 is an irrational number

1. let us assume that 2+√3 is a rational number
2. 2+√3= a/b
3. √3=a/b-2
4. √3= a-2b/b

• here a,b are any Integers a-2b are rational number
• but√3is an irrational number
• so our assumption is 2+√3 is rational number is wrong
• hence 2+√3 is an irrational number
