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

Answer:

b) $6\sqrt{2}$ irrational

Step-by-step explanation:

We are given two irrational numbers $\sqrt{50}$ and $\sqrt{2}$ and asked to find their sum and determine whether the result is rational or irrational.

Let us first simplify the first irrational number $\sqrt{50}$

$\sqrt{50} = \sqrt{25 \times 2}= \sqrt{25} \times \sqrt{2}=5\sqrt{2}$

Therefore

$\sqrt{50} = 5\sqrt{2}$

Now

$5\sqrt{2}+\sqrt{2}= \sqrt{2}(5+1)$

$=6\sqrt{2}$

Which is again an irrational number.

Hence our option B is correct
