Question 326866: Are each of the statements below true or false? Explain you answer.
Part 1
sq rt (a) + sq rt (b) = sq rt (a+b)
Part 2
The numerator and denominator of the following must be multiplied by sq rt (3) to rationalize 3/3+ sq rt (3) . Explain why.
Thank you for your help!
My thoughts to the first part, the principal square root of a non-negative number is its non-negative square root the symbol sq rt (a) represents the principal square root of a. Therefore a and b can represent any number...
Part one is false.
Part 2 is also false because we would multiply by 1. I am not quite sure if I completely understand...
Again Thank you!!

1) False, See Answer 234051.

2) False, to rationalize you need to yes multiply by 1 but the numerator and denominator have to equal since the denominator is so that when you multiply it out the square root terms cancel.

If you only multiply by
You still have a square root in the denominator.
