simplify (frac{10}{sqrt{32}})
-
A.
(frac{5}{4}sqrt{2}) -
B.
(frac{4}{5}sqrt{2}) -
C.
(frac{5}{16}sqrt{2}) -
D.
(frac{16}{5}sqrt{2})
Correct Answer: Option A
Explanation
(frac{10}{sqrt{32}}=frac{10}{sqrt{16times 2}} = frac{10}{4sqrt{2}}\
frac{10times sqrt{2}}{4sqrt{2}timessqrt{2}}=frac{10sqrt{2}}{4times 2}= frac{5}{4}sqrt{2})
