simplify 2 over 7

Question

simplify square root 2 over 7 square root

Answer 1

Your statement is not clear.

 

I'll assume: √(2)/√(7)

 

= √(2/7)

 

Multiply fraction by 7/7:

 

= √(14/49)

 

= √(14) / √(49)

 

= √(14) / 7

 

But if you meant √(√(2)/7) then

 

= √(√(2/49))

 

= √(√(98/7^4))

 

= 98^(1/4) / 7

Answer 2

√(2/7) can not be simplified , because 2, and 7 are both prime numbers , and don't have any common factor other than 1.

 

  We can only find its  approximate value by calculator:

 

    √(2/7) = √2 /√7 = 1.414/2.645 = 0.869
