Please help me with this surds question. Explain how you got your answer.

Answer:
1/5
Step-by-step explanation:
b and c = [tex]\sqrt{50}[/tex] because 10 x 5 = 50
therefore the fraction is √2/ √50
to simplify you need to simplify the √50 into a number of √2 as the top is √2
√50 = √25 x √2
= 5√2
√2/5√2 = 1/5 if you divide both top and bottom by √2
