sqrt of 8 = 1/2 sqrt 2. sqrt 16 = 4. Therefore the answer is 1/2 sqrt2. QED

10 square roots of 8 divided by the square root of 16:
the square root of 16 is 4, so you can write this as a fraction 10*sqrt 8 OVER 4
Then simply to 5*sqrt 8 over 2

go one more step and take sqrt of 8 as 2 sqrt 2
then the answer would be = 5 sqrt 2
