yes it is an irrational

Step-by-step explanation:

let me have to assume that 8+2root5 is rational.rational numbers are in the form of p/q.

then do s.o.b.s

u get one answers

conclusion contradiction to our assumption is wrong that 8+2root5 I a rational number.it is a fact that 8+2root5 is an irrational

Answer 2

Answer:

let 8+2√5 is a rational number

8+2√5=a/b

2√5=a-8b/b

√5=a-8b/2b

√5 can't be a factor of both a and b

so it is our contradiction that 8+2√5 is a rational number so 8+2√5 is an irrational numbet
