Answer 1

answer.

question 2.

à.555/1000

b.29568/1000

c.9315315....../1000000.......

d.357417417..../1000000....

e.30219/100

question 9.

a.-0.7142857143

b.0.818181818181

c.2.2360679775

d.9.30769230769

e.3.625

question 4.

letlet 5 + under root 7 is rational number where it can be written in p / q form where p and q (0=/q)and they are coprime number

5+√7= p/q

p/q-5=√7

√7=p-5q

q

here p-5q is a rational number but√7 is irrational number.

since ,rational is not equal to irrational

this contradiction has arises from our wrong assumption.

hence,5+√7 is irrational number
