Find the answer for the 7th question. Urgent

Answer 1

Answer:

22

Step-by-step explanation:

$\sqrt{2116} = 46 \\ \sqrt{1764} = 42 \\ therefore \\ \sqrt{0.2116} = 0.46 \\ \sqrt{0.1764} = 0.42$

$\sqrt{0.2116} + \sqrt{0.1764} \div \sqrt{0.2116} - \sqrt{0.1764} \\ = 0.46 + 0.42 \div 0.46 - 0.42 \\ = 0.88 \div 0.04 \\ = 22$
