Simplify (frac{sqrt{128}}{sqrt{32} – 2sqrt{2}})
-
A.
(2sqrt{2}) -
B.
(3sqrt{2}) -
C.
3 -
D.
4
Correct Answer: Option D
Explanation
(sqrt{128} = sqrt{64times2} = 8sqrt{2})
(sqrt{32} = sqrt{16times2} = 4sqrt{2})
Simplifying, we have (frac{8sqrt{2}}{4sqrt{2} – 2sqrt{2}} = frac{8sqrt{2}}{2sqrt{2}})
= 4
