Question

show that 4 root 2 is an irrational number​

Answer 1

Answer:

Step-by-step explanation:

Let 4√2 be rational number

Then 4√2=p/q

where q≠0, p and q are integers

4√2=p/q

√2=p/4q

Where √2 is irrational and

p/4q is rational

Our assumption is wrong,because LHS≠RHS

So 4√2 is a irrational number

Answer 2

answer 4root2 is rational no

4root2=p/q[p and q is co prime no]

root3= p/2q

root3 is irrational no

LHS is not equal RHS

IT IS CONDRICTION asuuming is wrong 4root 2is an irrational no
