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

Answer 1

Answer:

1/5

Step-by-step explanation:

b and c = $\sqrt{50}$   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
