It also has instructions for manually calculating the answer. It is very easy and well explained.

Hope this helps.

you still have sq rt 3 in the denominator — you can’t leave it there, so multiply both numerator and denominator by sq rt 3

your numerator is now sq rt 7 times sq rt 3, which is equivalent to sq rt 21, another irrational number, so leave that alone.

your denominator is 2 times 3 or 6

the final answer is sq rt 21/ 6
