3453
5556
6016
13453
Correct answer is A
4321\(_7\) + 1234\(_7\) = 5555\(_7\)
Missing number = 12341\(_7\) - 5555\(_7\)
= 3453\(_7\)
Simplify \(\frac{10}{\sqrt{32}}\)
\(\frac{5}{4}\sqrt{2}\)
\(\frac{4}{5}\sqrt{2}\)
\(\frac{5}{16}\sqrt{2}\)
\(\frac{16}{5}\sqrt{2}\)
Correct answer is A
\(\frac{10}{\sqrt{32}}=\frac{10}{\sqrt{16\times 2}} = \frac{10}{4\sqrt{2}}\\
\frac{10\times \sqrt{2}}{4\sqrt{2}\times\sqrt{2}}=\frac{10\sqrt{2}}{4\times 2}= \frac{5}{4}\sqrt{2}\)
