\[
\sqrt{\frac{1}{6} \div \frac{1}{6} \div \frac{1}{6} \div \frac{1}{6}}=?
\]
a) 1
b) 6
c) 25
d) N.A.
Therefore, \(\sqrt{\frac{1}{6} \div \frac{1}{6} \div \frac{1}{6} \div \frac{1}{6}} = \boxed{1}\).
Step 1 :First let's convert each division operation into multiplication by the reciprocal. So, \(\frac{1}{6} \div \frac{1}{6} \div \frac{1}{6} \div \frac{1}{6}\) becomes \(\frac{1}{6} \cdot 6 \cdot 6 \cdot 6\).
Step 2 :This simplifies to \(\frac{1}{6} \cdot 6 \cdot 6 \cdot 6 = 1 \cdot 1 \cdot 1 \cdot 1 = 1\).
Step 3 :Now we take the square root of 1, which is also 1. So, \(\sqrt{1} = 1\).
Step 4 :Therefore, \(\sqrt{\frac{1}{6} \div \frac{1}{6} \div \frac{1}{6} \div \frac{1}{6}} = \boxed{1}\).
