Which choice is equivalent to the expression below?
√50 -√2

The simplified form of the expression √50 - √2 is 4√2.
Given the expression in the question;
√50 - √2
To evaluate, first we simplify each term
√50 - √2
Factor out 25 from 50
√( 25(2) ) - √2
Now, rewrite 25 as 5²
√( 5²(2) ) - √2
Take the square root of 5² to pull it out of the radical
5√2 - √2
Now, subtract √2 from 5√2
4√2
Therefore, the simplified form is 4√2.
Option C) 4√2 is the correct answer.
