√4,9 : √10

To simplify the expression \(\frac{\sqrt{4.9}}{\sqrt{10}}\), we can rewrite it as:

\[ \frac{\sqrt{4.9}}{\sqrt{10}} = \sqrt{\frac{4.9}{10}} \]

Next, calculate \(\frac{4.9}{10}\):

\[ \frac{4.9}{10} = 0.49 \]

Now, we can take the square root:

\[ \sqrt{0.49} = 0.7 \]

Thus, \(\frac{\sqrt{4.9}}{\sqrt{10}} = 0.7\).

So the final answer is:

\[ 0.7 \]
