    does it help to know that \(75=25\times 3\)?

    so \[\sqrt{75}=\sqrt{25\times 3}=\sqrt{25}\times \sqrt3\]

    you can enter in the equation and it gives you the answer

    you end up with \[5\sqrt3+\sqrt3\] combine like terms to finish

    5x+x=6x and same way, it follows that 5√3 + √3 = ?

    you are adding the "square-root-of-3" five times, PLUS "square-root-of-3" one time.

    you are adding the number of times of which you have a √3. you have five square roots of 3, and then you add one more square root of 3. how many square roots of 3 do you have together?
