Question

An expression is shown below: square root of 50 plus the square root of 2 Which statement is true about the expression?

Answer 1

the last one i think hope its right

Answer 2

b)
`6√(2)` irrational

Explanation:

We are given two irrational numbers
`√(50)` and
`√(2)` and asked to find their sum and determine whether the result is rational or irrational.

Let us first simplify the first irrational number
`√(50)`

`√(50) = √(25 * 2)= √(25) * √(2)=5√(2)`

Therefore

`√(50) = 5√(2)`

Now

`5√(2)+√(2)= √(2)(5+1)`

`=6√(2)`

Which is again an irrational number.

Hence our option B is correct
